Definition: Three-Step Equation

Back

An equation that requires three steps to isolate the variable and solve for its value.

Front

Step 1 in solving equations: Combine like terms

Back

Combine terms that have the same variable or constant to simplify the equation.

Front

Step 2 in solving equations: Use inverse operations

Back

Apply operations that reverse the effect of the current operation to isolate the variable.

Front

Step 3 in solving equations: Isolate the variable

Back

Rearrange the equation to get the variable by itself on one side.
