F(x)=2x+1 g(x)=x^(2)+2x-8 what are the solutions to the system of equations?

(-3,-5) & (3,7)

Step-by-step explanation:

x² + 2x - 8 = 2x + 1

x² + 2x - 2x - 8 - 1 = 0

x² - 9 = 0

(x - 3)(x + 3) = 0

x = -3, 3

When x = -3, y = 2(-3) + 1 = -5

When x = +3, y = 2(+3) + 1 = 7

(-3,-5) & (3,7) are the solutions
