-[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 -
