Consider the characteristics of the center, shape, spread, and any unusual features. Which statement correctly describes the data?

1.) 7x - 3(x - 4) = 8       Multiply/distribute 3 into (x - 4)

7x - 3x + 12 = 8

4x + 12 = 8   Subtract 12 on both sides

4x = -4        Divide 4 on both sides

x = -1

2.) 4x - 8 + 2x = 40

6x - 8 = 40      Add 8 on both sides

6x = 48     Divide 6 on both sides

x = 8

3.) 6x - 6 + 11 = 53

6x + 5 = 53   Subtract 5 on both sides

6x = 48   Divide 6 on both sides

x = 8

4.) 17 = x - 3x - 3

17 = -2x - 3    Add 3 on both sides

20 = -2x   Divide -2 on both sides

-10 = x
