Solve linear equations with more than one term Level 5
4a + 3 = 11
Solve linear equations with more than one term Level 5
4a + 3 = 114a + 3 = 11
Step 1 – cover up the term with the letter attached to it
Solve linear equations with more than one term Level 5
4a + 3 = 114a + 3 = 11
Step 1 – cover up the term with the letter attached to it
Step 2 – what must the blue box (4a) be?
Solve linear equations with more than one term Level 5
4a + 3 = 114a + 3 = 11
4a = 8
Step 1 – cover up the term with the letter attached to it
Step 2 – what must the blue box (4a) be?
Step 3 – write down what the blue box (4a) equals
Solve linear equations with more than one term Level 5
4a + 3 = 114a + 3 = 11
4a = 8a = 4
Step 1 – cover up the term with the letter attached to it
Step 2 – what must the blue box (4a) be?
Step 3 – write down what the blue box (4a) equals
Step 4 – solve the last step, like you did earlier
