Lesson 2.3 Solving 2+ Step Equations

Let’s Review…. What are one step and two step equations? An equation that can be solved with only one or two mathematical operations. When there are more steps, we call it a multi-step equation.

Solving Multi-step Equations The goal is still to get the variable by itself! Is that always possible?

There are actually three different possible outcomes when solving for a variable. 1. One solution 2. No Solutions 3. Infinitely Many Solutions

Let’s try some examples… Solve the following for the indicated variable: x = -8 No SolutionInfinitely Many Solutions X =

Your Turn… Solve the following for the indicated variable: n = 20 Infinitely many Solutions x = -7 No Solutions

Summary List all possible outcomes when solving multi-step equations. Classwork: Worksheet 3.4B Homework: Worksheet 3.4B
