use either substitution or elimination
4/x3/y=0
4y=3x

Precalc 
Reiny
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) ....
