use either substitution or elimination

4/x-3/y=0
4y=3x

1 answer

multiply the first equation by xy
4y - 3x = 0
4y = 3x

Your second equation is the same, so in effect , you were only given one equation.
There will be an infinite number of solutions.
e.g.
(0,0), (4,3), (-4,-3), (8,6) , (1.23, 0.9225) ....
