Solving Two Step Equations

Intro

Warm Up

Solve for the missing Variable

1. 5x = 25 2. x + 27 = 84

Two Step Equations

What is our goal?

To get the variable all by itself

Ex: x = 13

Two Step Equations

Tell me how you would solve the expressions if you knew what x was.

1. 4x + 13

2. - 11

Hint: Think Order of Operations

Steps to Solving Two Step Equations

1. Make sure all like terms are combined on each side of the equal sign

2. Think how you would normally solve the expression. (order of operations)

3. Work backwards and perform the opposite operation.

4. Be sure to…

Solve for x

1. 4x + 13 = 65

2. - 11 = 17

Examples

1. 9n + 18 = 81

2. + 3 = 8

3. 14 = 5k – 31

4. 7 = 3 +
