Solve 1 Step

100

x - 5 = 20

x = 25

200

-3x = 12

x = -4

300

x + 7 = 35

x = 28

400

n/4 = 5

n = 20

500

1/2x = 6

x = 12

Solve 2 Steps

100

3a - 15 = 6

a = 7

200

5k - 12 = 13

k = 5

300

50 + 6b = 86

b = 6

400

1/2d - 12 = 24

d = 72

500

-5/2a + 5 = 25

a = -8

Solve Multi-Step

100

4(a + 10) = 80

a = 10

200

8(a + 30) = 80

a = -20

300

5p – 7 – 3p = 9

p = 8

400

10x - 2x = 56

x = 7

500

4(x - 3) + 1 = 9

x = 5

Solve with variables on both sides

100

5x + 8 = 3x + 20

x = 6

200

-3b + 8 = 2b + 48

b = -8

300

3(x – 4) – 5 = 2(x + 1)

x = 19

400

4(y – 5) + 6 = 2(y + 7)

y = 14

500

5(x – 3) –2 = 2(2x + 1)+ 1

x = 20
