Back

x = -30.

Front

What is the second step after isolating the variable in a two-step equation?

Back

Perform the inverse operation to solve for the variable.

Front

Solve -2w + 10 = 56

Back

w = -23.

Front

What does it mean to isolate the variable in an equation?

Back

To isolate the variable means to get the variable alone on one side of the equation.

Front

Solve -3 + 2x = -1

Back

x = 1.

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable.
