Part A - Final Review SOE, SOI, and Exponent Rules

What is the variable that will be "eliminated"?

(Hint: They have to have opposite signs to eliminate)

5x - 4y = 11

5x + 4y = -14

• x variable

• y variables

• both variables

What would be the first step in finding the solution using elimination?

2x + 2y = -2

3x - 2y = 12

• you cannot solve this using elimination

• cross out the 2x and 3x

• The "y" will cancel. Add the "x's" and they other numbers.

• change to slope intercept form and graph
