How would you Solve the Equation?

52 = m - 7

• add 7 to both sides

• subtract -7 to both sides

• multiply 7 to both sides

• Add 52 to both sides

How would you solve the equation?

72 = 8 + b

• add 8 to each side

• subtract 72 from each side

• multiply each side by 8

• Add -8 (or subtract 8) to each side

What is the first step to solve this equation:

11 - 3x = 44

• Add 3 to both sides

• Subtract 11 (or add -11) to both sides

• Add 11 to both sides

• Divide 3 on both sides.

What is the second step to solve this equation:

-3x - 9 = 6

• Add 9 to both sides

• Subtract 9 (or add -9) to both sides

• Multiply -3 to both sides

• Divide -3 on both sides.

What are steps to solve this equation:

-4x - 12 = 4

• Subtract both sides by 12; then multiply both sides by -4

• Add -12 to both sides; then divide both sides by -4

• Add 12 to both sides; then divide both sides by -4

• Divide both sides by -4; then add -12 to both sides

What is the second step to the following equations?

 $24\ =\ \frac{w}{4\ }+12$  

• Add -12 (or subtract 12) from both sides

• Multiply both sides by -4

• Multiply both sides by 4

• Divide both sides by -4
