1 Step DP

100

18 = 3(3x - 6)

x = 4

200

3(t -12) = 27

t=21

300

0.5(-8+x)=34

x=76

400

1/4(x+7)=8

x=25

500

(5k+ 35) - 8 = 12

k=-3

Multi-Step DP

100

5(x-6)=-2x+19

x=7

200

-w + 4(w +3) = -12

w=-8

300

5(t - 3) - 2t = -30

t=-5

400

5(3x+2)-5=5x+55

x=5

500

3(x+5) + 4(5x-6) = 5(3x+2) +3(x+7)

x = 8
