Multistep Equations

100

2(x + 3) = 22

x = 8

200

2x + 3x - 4 = 1

x = 1

300

5 (x + 6) = -9x + 2

x = -2

400

8(1 + 5x) + 5 = 13 + 5x

x = 0

500

2(3x - 4) + 8 = 6

x = 1

Absolute Value

100

| x + 5 | = 9

x = 4 , x = -14 

200

| x - 6 | = 10

x= 16 , or x = -4 

300

3 | x - 4 | = 21

x =  11, or x = -3 

400

6 | x - 3 | = 42

x = 10  or x = -4 

500

4 | x + 2 | + 3 = 7

x=-1 or x=-3

Inequalities
