rearrange one of your equations so that you get both variables on one side, then substitute the other into it. Solve in terms of "x" or "y".

abb0t · Answer

$y-x^2 = -4$ 
and $y=-x^2+5$ substitue thhis equation into the top one.

$(-x^2+5)-x^2=-4$
solve for "x".
then sibstitue that vlue int he other.

Can you show me the steps once you substitute?  I;m getting lost in the square root part

abb0t · Answer

$-x^2-x^2+5=-4$

I'm not getting how to solve it after that step.  2x^2=-9

abb0t · Answer

divide by 2 and square both sides.
