    3y - (4x + 7) -y+11+ (2x-y+12)
    In this case you expand the brackets all the brackets (noting that -(4x+7) is
    -4x - 7):

    3y - 4x - 7 -y+11+ 2x - y + 12

    collect together all the terms with the same unknown:

    (3y - y - y) + (-4x + 2x) - 7 +11 +12

    tot up how many of each variable you have:

    (1y) + (-2x) + 16

    remove brackets:

    y - 2x +16
