    Well, let's see...

    A-mB=\frac{(nA-mC}{1+R}

    A(1+R)-mB(1+R)=nA-mC

    -mB(1+R)=nA-mC-A(1+R)

    -mB(1+R)+mC=nA-A(1+R)

    mB(1+R)-mC=A(1+R)-nA

    m(B(1+R)-C)=A(1+R)-nA

    m=\frac{A(1+R)-nA}{B(1+R)-C}

    I checked over this once and didn't see any errors. I hope I didn't overlook anything. I also see that math_helper has already attached a solution. I see it is equivalent to my own. Take your choice.
