    3x+4=-5x-3+15

    First combine like terms:

    3x+4=-5x+12

    Get x on one side:

    3x+4=-5x+12

    -3x - 3x

    4=-8x+12

    Next get x by itself:

    4=8x+12

    -12 - 12

    -8=8x

    Now divide one more time to get x by itself since 8x is 8 times x and we must do the opposite (:).

    -8/8=8x/8

    -1=x - --> x=1
