-[2x-(5x+2)]=2+(2x+7) help me please, i need step by step so that I won't get lost

• math -

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

3x + 2 = 9 + 2x

3x - 2x = 9 - 2

x = 7

Check:
-14 + 35 + 2 = 9 + 14
23 = 23

• math -

work 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

• go with Ms Sue's, scrap mine math -

should have put my glasses on !
