    If you're solving for b, that means you want to isolate b to one side.

    P = a + 2b + 3c

    Subtract 3c from both sides:

    P - 3c = a + 2b

    Subtract a from both sides:

    P - 3c - a = 2b

    Divide both sides by 2:

    b = (P - 3c - a) / 2

    What you do here is, isolate everything to solve for the variable b. Steps as following:

    P-3c=a+2b

    P-3c-a=2b

    (P-3c-a) / 2=b

    Final answer: (P-3c-a) / 2 = b
