How Fast You Solve These Simultaneous Equations?
x + 2y = 102x + 3y = 18
{ in 10 sec}
Galuh and Enin
1. Elimination by Substitution.
2. Elimination by making the coefficient equal.
3. Easy Trick of Cross-Multiplication (Direct)
x + 2y = 102x + 3y = 18DIFFERENT WAYS TO SOLVE
Galuh and Enin
Before we use the faster way, we must write zero to fill in the missing part of polynomial. So the polynomial become:
