    5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13

    -5(3x + 2) = -4(4x + 5) + 13 + (x - 3)

    4(4x + 5) = 5(3x + 2) + 13 + (x - 3)

    5(3x + 2) - 4(4x + 5) + 13 + (x - 3) = 0

    x can have any value.

    5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13

    -15x - 10 - x + 3 = -16x - 20 + 13

    -16x - 7 = -16x - 7

    x is all real numbers

    5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13

    - 15x - 10 - x + 3 = - 16x - 20 + 13

    - 16x - 7 = - 16x- 7

    - 16x + 16x = - 7 + 7

     0 = 0 <------True..

    Expand both sides

    -15x - 10 + 3 - x = -16x - 20 + 13

     

    The x cancels out.

    -7 = - 7

    True
