Write out your fraction problem. 3 over 5 plus x over x equals 5 over 6. Next, you need to make the fractions equivalent. The multiples I used were 6 and 5.

(18 over 30 plus x over x equals 25 over 30. Subtract 25 from 18. Your answer is 7. Dont forget the other half of your fraction! Your final answer is 7 over 30.
