Modeling Two-Step Equations

Solve for x

• x = 2

• x = -2

• x = -10

• x = 4

What is the first step to solve this equation?

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

13 = 11 - 4x

• -2

• 1/2

• -1/2

• 2

-5z+5=-30

• z=7

• z=6

• z=5

• z=35
