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.
