Equations

One Step

100

x + 5 = 13

x = 8

200

x/5 = 25

x = 125

300

-3y = 18

y = -6

400

3 - x = 14

x = -11

500

-5 / a = -20

a = 1/4

Two Step

100

3x + 5 = 14

x = 3

200

x/5 - 3 = 9

x = 60

300

(x + 7) / 2 = 14

x = 21

400

(x+3) / -4 = 7

x = -31

500

(7 - t) / -10 = -5 

x = -43

3 Step

100

(2x + 1) / 3 = 1

x = 1

200

(-2x - 5) / 3 = 15

x = -20

300

7(x+2) = -14

x = 0

400

3x + 4 = x + 5

x = 1/2 or 0.5

500

-7p - 28 = -10p + 16

p = 44/3
