Answer:

(3,7) ———— choice 4

Step-by-step explanation:

x - 2y = -11 ————(1)

5x + 2y = 29 ————(2)

Solve for x using first equation.

x = -11 + 2y          Plug in for x in second equation

5(-11 + 2y) + 2y = 29        Solve for y

-55 + 10y + 2y = 29

12y = 84

y = 7         Plug in for y using first equation

x - 2(7) = -11       Solve for x

x - 14 = -11

x = 3

I hope this helped and please mark me as brainliest!
