The answer for question 17 is A. you can solve this by adding the two equations. (x+y)+(x-y)=7+3 :: x+y+x-y=10 :: x+x=10 :: 2x=10 :: x=5. put x=5 in first equation. x+y=7 :: 5+y=7 :: y=7-5 :: y=2. Therefore, the answer is A=(5,7). Sorry i couldnt put it in the actual answer up there. The page was already filled. so i had to put it here. hope it helped.
