There are two curves:
$$S1: xy^2z - yz + 2xz =39$$
and
$$S2: 2x - 3y + 5z = 26$$



I tried substituting x, y, z into both equations alternatively to get an equation in two variables and then find the dependence of one variable on another. But, I am not able to get the solution.
Any help will be much appreciated.



Thank You.



I am able to substitute for x, y, and z, and as in this answer: Find the intersection between the following two curves in 3 unknown variables., I even get that equation, but from here I am having a problem.

Hint: From the first erquation we get
$$z=frac39xy^2+2x-y$$
plugging this in the second equation we obtain



$$2x^2y^2-3xy^3-26xy^2+4x^2-8xy+3y^2-52x+26y+195=0$$
this can be solved for $$x$$ or $$y$$



$$x^2(2y^2+4)+x(-3y^3+26y^2-8y-52)+3y^2+26y+195=0$$
Can you solve this?

  • You can solve the equation above for $x$ or $y$, $x$ is the better choice, since it is a quadratic equation.
