    -x+8+3x=x-6

    8+2x=x-6

    +6 + 6

    14+2x=x

    -2x - 2x

    14/-1=-x/-1

    -14=x

    First group the coefficients together on their side of the equal sign.

    -x + 3x = 2x.

    Then, since it is a positive number, subtract it from that side and the other side.

    On the other side, the x becomes - x.

    Add the 6 from the other side to the 8 to make 14.

    14 = - x

    Divide both sides by - 1, to get the answer.

    x = - 14
