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.

Solve the equation:

-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

Solve 8x = 40 for x.

• 320

• 48

• 32

• 5

Answer explanation

Undo multiplication with division. Divide by 8 on both sides of the equal sign.
