Answer:

8

Explanation:

I started by just choosing a value for x and then a value for y that would make the first equation true. -1 for x and -2 for y worked...

$-8(-1)+3(-2)=2\\8+(-6)=2\\8-6=2\\2=2$

...so I used them in the second expression:

$-32(-1)+12(-2)\\32-24\\8$

Values that would make the 1st equation true will result in the second expression equally 8.
