**Solving Two-Step Equations**

Let's Review One-Step Equations:

WARM-UP ANSWER

Y - 5 = 2

+5 +5

Y = 7

Ogres and Two-Step Equations

Two-Step Equation

HINT: Start from the

OUTSIDE

layer

Example: 5X - 6 = 9

Layer 1:

Add 6 to both sides

Layer 2:

Divide both sides by 5

Warm-Up!

Y - 5 = 2

QUESTIONS?

Finish the phrase:

Ogres are like onions, and two-step equations, they all have . . .

LAYERS!

5X + 3 = 8

Example 1 :

Example 2 :

5X - 6 = 9

+6 +6

5X = 15

5 5

X = 3

-3 + 2W = 11

-10 = 6 + 4X

EXIT TICKET:

Name:

4Y - 9 = 15

Fist to Five:

Fist: I'm completely lost!

One: I'm very confused.

Two: I'm still a little confused.

Three: I kind of understand!

Four: I can do this!

Five: I can teach others!

Outside Layer?

5X - 6 = 9
