Please re-write. Should this say y-6=2 and y+4=7?
bottom number y+4 and then 2 with a lind on bottom and 7
its suppposed to be y=
That doesn't make any sense. Sorry, but I don't know what you're trying to say.
For problems like these, you want to cross multiply. 7(y-6)=2(y+4), 7y-42=2y+8, 7y=2y+50, 5y=50, y=10. You can plug that in for a check and you get 4/14, whcih reduces to 2/7, so it works.
