    Step-by-step explanation:

    15 = 7 - / 2x/

    Subtract 7 from both sides (if it was negative you would add it)

    (15-7) = (7 - 7) - / 2x / now the seven is no longer there

    8 = - / 2x/

    Now divide 2 from both sides

    (8 / 2) = - / (2 / 2) x/

    4 = - / x/

    4 = - x

    Now the two is no longer there but the x would still be there because you divided it by 2 and not 2x
