Answer:

x=2, y=3

Step-by-step explanation:

If you are trying to solve for x and y here, you can use substitution. What you want to do is multiply the top equation by 8, to get 40x-16y-32=0, and 16y=40x-32. Then we substitute it into the bottom equation, to get 43x-86 = 0. Since 86/43 = 2, x = 2. Then we can plug x into either one to get that y = 3.
