What is the first step to solve the equation 9c + 3 = 39?

Back

Subtract 3 from both sides to get 9c = 36.

Front

What is the second step to solve the equation 9c = 36?

Back

Divide both sides by 9 to find c = 4.

Front

If Shawna paid $32 for a bike rental that costs $14 plus $3 per hour, how do you set up the equation?

Back

Set up the equation: 14 + 3h = 32, where h is the number of hours.

Front

How do you solve for h in the equation 14 + 3h = 32?

Back

Subtract 14 from both sides to get 3h = 18, then divide by 3 to find h = 6.

Front

Solve for x: -5x + 13 = -17.

Back

x = 6.
