Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 4ax+by=11ab
8ax-5by=ab
---------------
Multiply the 1st eq by 2 to get:
8ax + 2by = 22ab
8ax-5by = ab
-----------------
Subtract the 2nd from the 1st and solve for "y":
7by = 21ab
y = 3a
---------------
Substitute into 4ax+by = 11ab to solve for "x":
4ax + b(3a) = 11ab
Divide thru by a to get:
4x + 3b = 11b
4x = 8b
x = 2b
------------------
Solution: (2b,3a)
