The solution

You have entered [src] 
x2 + 7*x*y = -6
7xy+x2=−67 x y + x_{2} = -6 
9*y2 - x*y = 10
−xy+9y2=10- x y + 9 y_{2} = 10 
or
{7xy+x2=−6−xy+9y2=10\begin{cases}7 x y + x_{2} = -6\\- x y + 9 y_{2} = 10\end{cases}
Rapid solution
x1=9y2−10yx_{1} = \frac{9 y_{2} - 10}{y}
=
9y2−10y\frac{9 y_{2} - 10}{y}

=
(-10 + 9*y2)/y

x21=−63y2+64x_{2 1} = - 63 y_{2} + 64
