hi everyone, i have 3 equations and 3 unknowns:

x = (a/b) + c

y = (a/(b+1)) + c

z = (a/(b+7)) + c

where x, y, z are given in the problem (real #'s), and we need to find the values of a, b, and c.

can anyone tell me how to go about this problem? i tried rigourous algebra of solving and substituting but it became too difficult to isolate one of the variables a, b, or c.

thank you in advance!
