Answer:

(15,23)

Step-by-step explanation:

-4x+3y=9

5x-2y=29

Let's multiply the first equation by 2 and the second equation by 3, in order to have the same coefficient on y.

-8x+6y=18

15x-6y=87

Add these two equations together to eliminate y.

7x=105

x=15

Now, plug in x, to find y.

5(15)-2y=29

75-2y=29

-2y=-46

y=23
