    One solution is x = 0. The other depends on y.

    There will be two solutions for x:

    15xy-8x^2=0

    x(15y-8x)=0

    x=0 or 15y-8x=0

    15y=8x

    x=\frac{15y}{8} or x=0

    Factor...

    x(15y-8x)=0

    x=0

    15y=8x\Rightarrow\ \frac{x}{y}=\frac{15}{8}

    Hence, x=0 or x:y=15:8
