**Ms. Sue**, Sunday, October 13, 2013 at 10:57pm-[2x-(5x+2)]=2+(2x+7)

3x + 2 = 9 + 2x

3x - 2x = 9 - 2

x = 7

Check:

-14 + 35 + 2 = 9 + 14

23 = 23

**Reiny**, Sunday, October 13, 2013 at 11:00pmwork the inner brackets first

-[2x-(5x+2)]=2+(2x+7)

-2[2x - 5x -2] = 2 + 2x + 7

-2[-3x - 2] = 9 + 2x

6x + 4 = 9 + 2x

6x - 2x = 9 - 4

4x = 5

x = 5/4
