what is the x for each problem:
x=3 x=11 x=1/2

0.8x + 5 = 0.2(40 - x)

2(x - 5) + 7 = x + 8

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

5(x - 1) - 6x = -11x

3x + 3 = 2(x + 7)

1/2(x+8)+3/2x=10

1/2x+1/4= x

0.8x + 5 = 0.2(40 - x)       x=3

2(x - 5) + 7 = x + 8            x=11

6(x + 2) - x = 4(x + 4) + 7  x=11

5(x - 1) - 6x = -11x              x=1/2

3x + 3 = 2(x + 7)                x=11

1/2(x+8)+3/2x=10              x=3

1/2x+1/4= x                        x=1/2
