simultaneous equation, solve for x & y I'm stuck solving what appears to be a simple simultaneous equation. A point in the right direction would be appreciated. 
Solve the simultaneous equations for x and y:
$y=x^{2}+7x-11$,
$y=x-1$
my workings:
$0=x^{2}+6x-10$
$10=x^{2}+6x$
$10/x=x+6$
From here i go around in circles trying to solve for $x$. I'm sure i've missed something basic. Thank you in advance. 

Once you have
$x^2+6x-10=0$,
you have a standard quadratic equation.
Solve it.
