One way to solve an equation is to get the _________ alone on one side of the equal side. (hint, number is not what I am looking for)

variable

200

You can get the variable alone by using the _______ __________, which are operations that undo one another. 

Inverse Operations

300

What is my first step in this problem?

6x-2=22

add 2 to both sides

400

When solving a two-step equation you find the solution that makes the ______________ true. 

equation or problem

500

Solve for X;

-6x-7=-13

x=1

What in the inverse is that?

100

What inverse operation would I use in 2-6k=14 first

subtract 2 from both sides

200

What Inverse Operation would for 

(2x)/5=20

multiply both sides by 5

300

What is my first step in this problem?

 2+3x=20

Inverse operation, subtract 2 from both sides

400

What is my first step in solving this problem?

-7+3p-5=6

Combine like terms, -7-5=-12
