Solve for x and y 9/x-4/y=8
1 answer:
You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time. Solving for x: </span><span>9/x-4/y=8 Mult all 3 terms by xy to eliminate the fractions. 9(xy)/x - 4xy/y = 8xy => 9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y) then 9y = x [ 4(1+2y) ] 9y therefore x = ------------ 4(1+2y) Solve for y using a similar approach. </span>
