This is about adding and subtracting expressions with the same denominators. Go back to simple arithmetic such as 5/62/6. All you do is go right across and 1.)Add or subtract the numerator (52). 2.) Keep the denominator. 3.) Change to lowest terms. Use the same general rules. In the problem: 9f+6g/6  6g9f/6, you put the numerator all together so that it reads: 9f +6g  (6g9f) put parenthesis around the second part so you don't forget to distribute the whole part. The 6g's cancel out and you get 9f plus 9f which is 18f/6 which equals 3f. Another problem: y^2/(y+5) + 5y/(y+5). It goes down to y^2+5y/(y+5). Combine to lowest terms. The (y+5)'s cancel out and you get the answer as y.
