The answer should be 6f. You multiply the 3 and the 2 and then put the f at the end (:
9x + 18 /4 + -5x + 24 / 4
So you can use substitution...which is where you have Y all alone on one side of your equation and then plug it in to the other equation...2x-5=-3x+10 and you.solve for X. So x= 3. Then plug 3 into one of the original equations... Y=2(3)+5. So Y= 11.
