• Add 62 to each side.

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

What step would you have to take to solve the following equation?

9x=153

• multiply by 9 on both sides

• divide by 9 on both sides

• add 9 to both sides

• subtract 9 from both sides

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
