Answer:
(15,23)
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
