    a = - 1/2b + 1/6w + 2/3

    Step-by-step explanation:

    w = 3 (2a+b) - 4

    Add 4 on both sides.

    w + 4 = 3 (2a+b)

    Divide 3 into both sides.

    w/3 + 4/3 = 2a+b

    Subtract b on both sides.

    w/3 + 4/3 - b = 2a

    Divide 2 into both parts.

    w/3/2 + 4/3/2 - b/2 = a

    a = w/6 + 4/6 - b/2

    a = 1/6w + 2/3 - 1/2b

    a = (w-3b+4) / 6

    Step-by-step explanation:

    w = 3 (2a+b) - 4

    w=6a+3b-4

    6a = w-3b+4

    a = (w-3b+4) / 6
