Answer 1

x = 4, x = -6

Explanation:

Plato

Answer 2

(4, -6)

Explanation:

y= x² - 2x - 19

y + 4x = 5

x² - 2x - 19 + 4x = 5

x² + 2x = 5 + 19

x² + 2x = 24

x² + 2x - 24

x² + 6x - 4x - 24

x(x + 6) - 4(x + 6)

(x - 4) (x + 6)

x = 4, x = -6

The pair of points representing the solution set of this system of equations is (-6, 29) and (4, -6)
