1 and 2-step equations

100

Solve for x.

7 = x/9

x = 63

200

Solve for c.

c - -29 = 699

c = 670

300

Solve for x.

8 - 2x = 4

x = 2

400

Solve for y.

y/9 + 44 = 54

y = 90

500

Solve for v.

 (v + 430) = -2

6     

y = -442

Multi-step equations

100

Solve for p.

46 = 2(p + 14)

p = 9

200

13(p - 992) = 78

p = 998

300

Solve for x.

16x - 13x = 15

x = 5

400

14k - 5k - 2k - 2k + 4k = 18

k = 2

500

Solve for d.

13d - 9d - -6 = 18

d = 3
