Solving One and Two-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step, typically by performing one operation (addition, subtraction, multiplication, or division) to isolate the variable.

Front

What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to isolate the variable, usually involving both addition or subtraction and multiplication or division.
