What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides
• add 5 to both sides
• subtract 15 from both sides
• subtract 5 from both sides

The variable, k, is being divided by 11. How should you show your work to isolate the variable?

• Divide both sides by 11
• Multiply both sides by 11.
• Add 11 to both sides.
• Subtract 11 to both sides.

2x + 6 = 18

• x = 12

• x = -6

• x = 6

• x = -12

4x - 5 = 11

• x = -4

• x = 6

• x = -6

• x = 4

-3x + 8 = -1

• x = 5

• x = 3

• x = -5

• x = -3

14 = 6x - 4

• x = -3

• x = 10

• x = -10

• x = 3
