300

What is a number all by itself WITHOUT a variable in an expression? For example, the 7 in 3x +7 = 90

Constant 

400

What are the coefficients in this expression?

-2x + 3y

Addition and Subtraction

100

Solve. 

x + 2 = 8

x = 6

200

Solve. 

x - 10 = 12

x = 22

300

Solve. 

26 = x + 14

x = 12

400

- 6 + x = 12 

x = 18

500
