# Solving for $x$ in a system of equations with 2 variables

by Maria Mercedes   Last Updated November 18, 2018 21:20 PM

$$a^2-b^2-c^2=x^2-y^2\quad \&\quad ab=xy$$

Hi. So I have been trying to solve this equation (I'm looking for $$x$$, and $$x$$ and $$y$$ are the only variables) but I just can't find a solution. Please help. How do I find an expression for $$x$$?
