Answer:
x = 1, y = 4, or x = -2, y = 1
Step-by-step explanation:
y = -x^2 + 5
-x + y = 3
Use substitution to solve for the equation
-x + (-x^2 + 5) = 3
-x^2 - x + 5 = 3 (simplifying)
-x^2 -x + 2 = 0 (simplifying)
(-x + 1)(x+2) = 0 (factoring)
-x + 1 = 0 or x + 2 = 0
<em>x = 1, or x = -2 </em>
-x + y = 3
-(1) + y = 3, or -(-2) + y = 3
<em>y = 4, or y = 1</em>
just choose any one...
x = 1, y = 4
or x = -2, y = 1
(they both work)
