Solve using elimination 6x 9y 24 5x 4y 34 4 0 9 9 13 4 1

Solve using elimination 6x + 9y = -24 -5x - 4y = 34 (4, 0) (9, -9) (13, -4) (-10, 4)

6x + 9y = -24

-5x - 4y = 34

multiply equation 1 with 5 and equation 2 with 6

30x + 45y = -120

-30x - 24y = 204

add both equations:

21y = 84

y = 4

6x + 9y = -24

6x + 36 = -24

x = -10

(x,y) = (-10, 4)

correct option is 4.
