Solve this system of equations algebraically:

y + x = 19 - x2

x + y = 80

1. Isolate one variable in the system of equations. y = - x2 - x + 19

y = - x + 80

2. Use substitution to create a one-variable equation. - x + 80 = - x2 - x + 19

3. Solve to determine the unknown variable in the equation.

The system has
