Absolute Value

100

|x| = 10

x = 10, -10

200

|x + 2| = 3

x = 1, -5

300

|3x + 9| - 10 =  -4

x = -1, -5

400

|3x -4| = |x|

x = 1, 2

500

|4x - 10| = 2|3x + 1|

x = 0.8

Solve for a Variable

100

A = LW

Solve for W

W = A/L

200

3y + 4x = 9

Solve for y

y = -4/3x + 3

300

y = 3x + 5xz

Solve for x

x = y/3 + 5z

400

S = 2lw + 2lh + 2wh 

Solve for l

l = S - 2wh/2w + 2h

500

C = 5/9(F - 32)

Solve for F

F = 9/5C  + 32
