Two-Step Equations

After you subtract 5 from both sides of the equation 3x + 5 = 20, what will the equation look like?

• 3x = 25

• 3x = 20

• 3x = 3

• 3x = 15

solve: 4x + 6 = 18

• Add 15 to both sides

• Subtract 15 from both sides

• Multiply by 4 on both sides

• Divide by 4 on both sides

• Add 6 on both sides

• Subtract 6 on both sides

• Divide by -9 on both sides

• Divide by 9 on both sides

• -3

• 3

• 12

• -4
