1 Step and 2 Step Equations

The goal when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• combine like terms.

What is a 1-step problem?

• A problem where multiple operations are present.
• A problem where the variable is missing.
• An equation where only one step is needed to solve it.
• An equation where two steps are needed to solve it.
