The ratio of the number of adults to the number of students at the prom has to be 1:10. There are 477 more students than adults. How many adults are at the prom?

1/2x+477=10/2x?
Answered by Steve
if there are x adults, there are 10x students.

10x = x+477

Not sure where the 2x came from, or why the divisions.
