Two-Step Equations

100

2x + 3 = 11

x = 4

200

4x + 8 = 28

x = 5

300

3x - 4 = 14

x = 6

400

6 - x = 8

x = -2

500

x/2 - 4 = 3

x = 14

Variables on Both Sides

100

4x - 6 = 2x

x = 3

200

8x = 5x + 21

x = 7

300

5x + 3 = 4x - 3

x = -6

400

3x - 2 = 8x + 13

x = -3

500

3/5 x - 15 = 6/5 x + 12

x = -45

Multi-Step Equations

100

5(x - 7) = 25

x = 12

200

8(3x + 6) = 9(2x - 4)

x = -14

300

6(2x - 8) + 3 = 15

x = 5

400

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

x = 2

500

Double Jeopardy!! 

 2(3x + 5) = 5(2x - 4) - 4x

NO SOLUTION!!!
