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)
