Front

What is the first step in solving a two-step equation?

Back

The first step is to eliminate the constant term from one side of the equation by performing the inverse operation (addition or subtraction).

Front

What is the second step in solving a two-step equation?

Back

The second step is to isolate the variable by performing the inverse operation on the coefficient (multiplication or division).

Front

What does it mean to 'isolate the variable'?

Back

Isolating the variable means to manipulate the equation so that the variable is alone on one side of the equation, making it easy to determine its value.
