Solve: x + 9 = 21

x = 12

3k + 4k  + 8 = 22

k = 2

Solve: -7x - 12 = 16

x = -4

V = lwh

Find v when l = 2, w = 3 and h = 4

2 x 3 x 4 = 24

200

18 + s = 12

x = -6

200

x + 4 + 6 = 23

x = 13

200

21 = 8x + 5

x = 2

V= lwh

find w when v = 24, l = 2 and h = 3

24 = (2)(3)(w)

24 = 6w

4 = w

12 = z - 5

z =  17

300

3z + 5 - 2z = 9

z = 4

n/3 + 9 = 12

n = 9

P = 2l + 2w

Find P when l = 4 and w = 8

P = 2(4) + 2(8)

P = 8 + 16

P = 24

54/x = 6

9 = x

P = 2l + 2w

Find l when p = 50 and 2 = 5

50 = 2l + 2(5)

50 = 2l + 10

40 = 2l

l = 20

h + 23 = 11

h = 3

A = lw

Find l when A = 12 and w = 3

12 = 3l

4 = l
