Two-Step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

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

Back

The first step is usually to isolate the variable by performing the inverse operation of the constant term.

Front

Solve for a: 2a + 3 = 7

Back

a = 2

Front

Solve for a: 5a - 11 = 4

Back

a = 3
