Back

g = -1

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power.

Front

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

Back

The first step is usually to eliminate the constant term from one side of the equation.

Front

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

Back

The second step is to divide or multiply to solve for the variable.
