Sorry, looked into this a bit more and see that "cheating" is an issue. This is for my own benefit. Im working on some practice tests, and its multiple choice. The way that I would solve this would be (456+34y)/5=3478_____(490y)/5=3478_____(490y)=17390_____y=35.489. This is the wrong answer though, just not sure which step im messing up. Thanks.
Are you SURE 456 is correct? I think it should be 458...
