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 by performing the same operation on both sides 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, typically involving addition or subtraction followed by multiplication or division.
