Answer:

8+7x+4y

Step-by-step explanation:

15+12x-5x+4y-7

15, and -7 are like terms.     12x, and -5x are like terms.      4y does not have a like term.

So we substract 7 from 15 and that equals 8.

Then we substract 5x from 12x and that equals 7x.

And we leave the 4y alone.

Hope this help you.
