Equations I

100

3x - 8 = 4 

x = 4

200

4(2x + 6) = 8

x = -2

300

-(5x - 7) + 4 = -4

x = 3

400

3x - 7x + 7 - 10 = 9

x = -3

500

-(6x + 9) - 4(4x - 3) = 25

x = -1

Equations 2

100

8x - 2 = -9 + 7

x = 0

200

-8 = -(x + 4) 

x = 4

300

-18 - 6k = 6(1 + 3k)

k = -1

400

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

x = 3

500

-3(4x + 4) + 4(6x + 1) = 2x + 42

x = 5
