I find myself in the odd situation of actually having to use algebra in real life many many years after leaving school!
If C = A + A * B, how do I find A from knowing B and C? If it makes any difference, A,B & C are all greater than zero.
Why can't you just subtract the product of (A*B) from C? Would this be wrong?
I don't think my method would answer his question because it doesn't simply the equation to A in terms of B and C (it is A in terms of A,B, and C) amd I right?
So...
C = A + (AB) -> (-AB)
C - AB = A
