Question 181505
I am having a hard time trying to solve this system of eqaution. I hope you can help me. 
X² - y = -2
X - y = 2 
-----------
x - y = 2 --> y = x-2
Sub into the 1st eqn
{{{x^2 -(x-2) = -2}}}
{{{x^2 -x +4 = 0}}}
*[invoke solve_quadratic_equation 1,-1,4]
--------------
Then solve for y, y = x-2
