3. What step needs to be taken to perform elimination?
2x+2y=20
-x+6y=10

• Combine them
• Set them equal
• Find the blob
• Multiply the bottom by 2

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

2x + 2y = -2

3x - 2y = 12

• you cannot solve this using eliminiation

• cross out the 2x and 3x

• cross out the 2y and -2y

• change to slope intercept form and graph
