Slide 2 STAIR Project by Katlyn Witt Click on the arrow to
advance to the next page Slide 3 Just like the title states, this
STAIR will teach you how to solve multi-step equations. You can
navigate through this presentation using the buttons at the bottom
of the screen. The arrow buttons will take you back and forth
between the different pages. The video camera button will take you
back to the video mini-lesson, in the event you want to review or
brush up on your skills. Slide 4 Use the distributive property to
simplify an equation. Use the addition, subtraction,
multiplication, and division properties of equality to solve an
equation. A1.2.1 A1.2.3 Slide 5 Click the video to play. Slide 6
Using the steps you learned in the video, solve the following
equations. You will want to have a writing utensil, paper, and a
calculator (but its not necessary). Choose the best answer for each
of the equations. Advance to the next page to begin. Slide 7 2x +
10 = 6 x = - 2 I dont know where to start I dont know where to
start x = x = 8 Slide 8 You got the problem correct! Click the
arrow in the corner to go to the next question. Slide 9 2x and 10
are not considered like terms. Try again! Back to Question Slide 10
It looks like you added 10 instead of subtracting it. Try again!
Back to Question Slide 11 The first thing you need to do is use the
subtraction property of equality. Back to Question Slide 12 Click
the video to play. Back to Question Slide 13 13 4x = -15 x = -1.67
I dont know where to start I dont know where to start x = 7 x =
Slide 14 You got the problem correct! Click the arrow in the corner
to go to the next question. Slide 15 13 and -4x are not like terms.
Try again! Back to Question Slide 16 It looks like you added 13
instead of subtracting it from both sides. Try again! Back to
Question Slide 17 The 13 in front is positive, so you need to use
the subtraction property of equality. Back to Question Slide 18
Click the video to play. Back to Question Slide 19 x + 5 = 25 x =
40 I dont know where to start I dont know where to start x = 60 x =
45 Slide 20 You got the problem correct! Click the arrow in the
corner to go to the next question. Slide 21 It looks like you added
5 to both sides instead of subtracting 5. Try again! Back to
Question Slide 22 When getting rid of a fraction, you need to
multiply everything by 2. You forgot to multiply the middle term as
well. Try again! Back to Question Slide 23 Start by using the
subtraction property of equality to move the 5 to the other side.
Back to Question Slide 24 Click the video to play. Back to Question
Slide 25 3x 4 + 5x = 12 x = - 8 I dont know where to start I dont
know where to start x = 2 x = 1 Slide 26 You got the problem
correct! Click the arrow in the corner to go to the next question.
Slide 27 Be careful with combining like terms. 3x + 5x is not -2x.
Try again! Back to Question Slide 28 It looks like you subtracted 4
from both sides instead of adding 4. Try again! Back to Question
Slide 29 Start by combining like terms on the left side. Back to
Question Slide 30 Click the video to play. Back to Question Slide
31 12x + 10 = 3x + 55 x = 4.3 I dont know where to start I dont
know where to start x = 2.6 x = 5 Slide 32 You got the problem
correct! Click the arrow in the corner to go to the next question.
Slide 33 It looks like you added on both sides instead of
subtracting. Try again! Back to Question Slide 34 You cant combine
the xs and the constants (just the numbers). Try again! Back to
Question Slide 35 Start with the subtraction property of equality.
Back to Question Slide 36 Click the video to play. Back to Question
Slide 37 4x + 5 2x = 10 + 3x x = - 5 I dont know where to start I
dont know where to start x = 1.67 x = - 15 Slide 38 You got the
problem correct! Click the arrow in the corner to go to the next
question. Slide 39 It looks like you combined like terms
incorrectly. 4x 2x is not 6x. Try again! Back to Question Slide 40
It looks like you added 5 to both sides instead of subtracting 5.
Try again! Back to Question Slide 41 You need to combine like terms
on the left first. Back to Question Slide 42 Click the video to
play. Back to Question Slide 43 4(x 6) = 16 x = 5.5 I dont know
where to start I dont know where to start x = 0.67 x = 10 Slide 44
You got the problem correct! Click the arrow in the corner to go to
the next question. Slide 45 When distributing the 4, make sure you
also multiply 4 times - 6. Try again! Back to Question Slide 46 You
cannot combine the -6 and the x inside the parenthesis. Try again!
Back to Question Slide 47 Distribute the 4 by multiplying it into
the parenthesis. Back to Question Slide 48 Click the video to play.
Back to Question Slide 49 7(x + 3) = x - 4 x = -0.2 I dont know
where to start I dont know where to start x = 2.1 x = - 4 Slide 50
You got the problem correct! Click the arrow in the corner to go to
the next question. Slide 51 You cannot combine the x and the 3. Try
again! Back to Question Slide 52 It looks like you added 21 to both
sides instead of subtracting it. Try again! Back to Question Slide
53 Distribute the 7 by multiplying it into the parenthesis. Back to
Question Slide 54 Click the video to play. Back to Question Slide
55 5(3 + 2x) = 35 x = 2 I dont know where to start I dont know
where to start x = 10 x = 13.5 Slide 56 You got the problem
correct! Click the arrow in the corner to go to the next question.
Slide 57 You need to be sure to distribute the 5 to both terms in
the parenthesis. Try again! Back to Question Slide 58 It looks like
you subtracted the 5 that was in front of the parenthesis instead
of distributing it. Back to Question Slide 59 Distribute the 5 by
multiplying it into the parenthesis. Back to Question Slide 60
Click the video to play. Back to Question Slide 61 10(7x 6) = 30x +
20 x = -1 I dont know where to start I dont know where to start x =
1 x = 2 Slide 62 You got the problem correct! Click the arrow in
the corner to finish the STAIR. Slide 63 You cannot combine the 7x
and -6. Try again! Back to Question Slide 64 You cannot combine the
30x and the 20. Try again! Back to Question Slide 65 Distribute the
10 by multiplying it into the parentheses. Back to Question Slide
