Simple Equations

100

Solve x - 4 = -10

x = -6

200

-3x = -14

x = 14/3

300

4x - 6 = -14

x = -2

400

-x - 2 = -20

x = 18

500

-x/5 + 13 = 15

x = -10

Multistep Equations

100

-3x - 7x = -20

x = 2

200

8x - 2 = -9 +7x

x = -7

300

-8 = - (x+4)

x = 4

400

3k - 5 = -8 (6 + 5k)

k = -1

500

-5 (1 - 5x) + 5 (-8x - 2) = -4x - 8x

x = -5

Absolute Value Equations
