One Step Equations

100

x + 7 = 10

x= 3

200

3x = 36

x = 12

300

(1/2)x = 8

x = 16

400

(-2/3)x = 4

x= -6

500

(-1/2m)= -9

m = -18

Two Step Equations

100

3 + 2w = 15

w = 6

200

6x + 8 = 50

x=7

300

(x/2)-7 = 9

x = 32

400

15 = 9 - (1/2)x

x = -12

500

4 = (w + 8) / 9

 w = 28

Multi Step Equations

100

-7(3a -1) = 

a = -4

200

5n - 42 = 12n

n = - 6

300

-(6h +7) + 8 = -19

h = (10/3)

400

98(2w - 1) - 4w = -116

w= -9

500

-25 = (1/2)(10x - 2) +3x

x = -3

Variables on both sides

100

-6x + 14 = 12 - 8x

x= -1

200

-15- 3w = 4w - 2w

- 3 = w

300

3x - 13 = 7(x+2) - 4(x-7)

No solution

400

8 - 8(1 + 3x) = 23 - x

x = -1

500

4y = 38 - (1/2)(4y +16)

y=5

Distributive Property

100

2( b + 3)

2b + 6

200

-(m + 3)

-m - 3

300

-x(y - 3)

-xy + 3

400

(1/4)(8x - 4) = 

2x - 1

500

-3(-9v-4) - 2(v -2)

25v + 16
