    19-3x=21+x

    Add 3x to both sides.

    19-3x+3x=21=x+3x

    19=21+4x

    Subtract 21 from both sides.

    19-21=21+4x-21

    -2=4x

    Divide both sides by 4.

    -1/2=x

    Hope this hleped!

    Subtract 19 from both sides

    -3x=2+x

    Subtract x from both sides

    -4x=2

    Divide both sides by - 4

    x=-1/2

    Final answer: x=-1/2
