Systems of Linear Equations
Which variable is EASIER to get rid of? Why?
3x + y = 10
5x - y = 14
The "y" variable because it's already set up to cancel out!

What do you need to multiply the equations by so that they're ready to solve?
4x + 2y = 10
3x + 5y = 4
Option 1: Multiply the top equation by 3 and the bottom equation by -4 (or switch the negatives!)
Option 2: Multiply the top equation by 5 and the bottom equation by -2 (or switch the negatives!)
