    I need a step-by-step way to complete these problems:

    A= P+Prt ; for P

    Ax+ By=C; for y

    A= P(1+rt); for r

    A= 1/2(B+b); for B

    D= C-s
    ----- for C

    Thanks for using BrainMass.

    A= P+Prt ; for P

    It is the same as
    A = P(1+rt), so dividing both sides by (1+rt), we have P=A/(1+rt)

    Ax+ ...
