I hope that you like logarithms. Hopefully there may be an easier solution than mine!

From equation #2

Substituting for x in equation #1

taking log of both sides to base

dividing through by y

to the power of

Example; say a = e =2.718 and b = 17 then y=1.764875.

from equation #2

finally

It is usual for letters from the first half of the alphabet to be considered as constants and letters from the last half of the alphabet to be variables. Therefore, if the question had been written more formally it might have said something like:

Solve the following system of equations for x and y, given the constants a and b. - August 24th 2009, 05:32 AMWilmer
