3x + 14y = 5xy
21y - x = 2xy
kindly solve the pair of linear equation
Answered by Steve
note from #2 that
x = 21y/(2y+1)

put that into #1 and you have

3*21y/(2y+1) + 14y = 5y*21y/(2y+1)
63y + 14y(2y+1) = 105y^2
77y^2-77y = 0
77y(y-1) = 0
Now you have two solutions for y. Use them to get associated solutions for x.

1.Divide the two equations by xy
2.You will now have two equations.
3.Solve it by multiplying and cancelling , and find x and y by substituting.
