Solve -7(11-4w)-15w=-27-(50-13w) show work

  • algebra -

    -7 ( 11 - 4w ) - 15 w = -27- ( 50 - 13 w ) =

    - 7 * 11 + 28 w - 15 w = - 27 - 50 + 13 w


    ( Remark : -7 * - 4 w = 28 w

    - ( -13 w ) = 13 w )


    -77 + 28 w - 15 w = - 27 - 50 + 13 w

    28 w - 15 w - 13 w = - 27 - 50 + 77

    0 = - 77 + 77

    0 = 0


    All values of w are solutions.
