Hi, I need help with this problem
[MATH]\begin{cases} x^2y+2xy^2+y^3=9 \\ x^3y-y^4=7\end{cases}[/MATH]
I tried factorization, but still not working. Also tried y=kx, but powers of equations are not the same so bad. Thanks.
 
Can we see your work so we can help you make progress so that you can solve your problem.
 
Actually after factoring you should be able to see a solution fairly easily.
