Front

What is the first step to solve the equation 4x - 5 = 11?

Back

Add 5 to both sides of the equation.

Front

What is the second step to solve the equation 2x + 6 = 18?

Back

Subtract 6 from both sides of the equation.

Front

What does it mean to perform the inverse operation?

Back

An inverse operation reverses the effect of the original operation (e.g., addition and subtraction are inverses).
