use either substitution or elimination

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

  • Pre-calc -

    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) ....
