Front

Solve the equation: 4(2x + 3) - 5 = 23

Back

x = 1.375

Front

Solve the equation: 6 - 2x = 10

Back

x = -2

Front

What is the first step to solve the equation 3x + 4 = 10?

Back

Subtract 4 from both sides to get 3x = 6.

Front

What is the second step to solve the equation 3x = 6?

Back

Divide both sides by 3 to get x = 2.
