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
