Two-Step Equations

100

Solve:

3x - 4 = 8

x = 4

200

What operation would you use to UNDO x/7

multiplication 

300

Solve:

-4y + 10 = 26 

y = -4 

400

Which operation would you do first, when trying to solve this for x?

5x - 11 = 32

add 11 to both sides

500

Solve:

2/3x + 4 = 10

x = 9 

Multistep Equations

100

What would you do first to solve this?

3(3x + 4) - 9 = 27

Distribute 

200

Solve: 

3x + 9x - 4x + 9 = 33 

x= 3

300

What are the three steps you need to follow to solve multistep equations?

2. Combine like terms

3. Get x by itself by using INVERSE OPERATIONS. 

400

What is the goal of solving a multistep equation? 

To isolate the variable 

500

Solve:
