INTRODUCTION TO 4.5: SOLVING 2 STEP EQUATIONS

R drive > Key > Week 6 > Wednesday > Intro to 4.5 PowerPoint

File > Save As > P drive > math > Week 6 > Intro to 4.5 PowerPoint

I’M THINKING OF A NUMBER…..

If you multiply it by 3 and add 2, the result is 8

* To solve the problem, you can use the “work backwards strategy”. Undo each operation in reverse order.

2X + 2 = 12

9 = 4 + 5X

4X + 3 = -9

3X – 3 = 6

WITH YOUR PARTNER Solve the following equations on a sheet of

paper using Algebra Tiles. For each problem: (1) Write the equation (2) Draw a picture of what you did (3) Write the solution

#1. 3x + 6 = 15 #2. -6 = 2x + 4 #3. 2x + -1 = 7 #4. -3x + 1 = -8

A FEW NOTES…..A 2 step equation contains 2

operations. To solve a 2 step equation, use inverse operations to undo each in reverse order of

the order of operations.

EXAMPLE 1SOLVE 3A + 9 = 33. CHECK YOUR SOLUTION
