Question 47061: How do I know if my answer is correct?
Subtract. Express your answer in simplest form. ( I had to use the backslash because the system would not write it correctly, the question shows a straight line between the 13x and 30 and the 4x and 15).
13x/30 - 4x/15

13X/30-4X/15 OR FINDING A COMMON DENOMINATOR BY MULTIPLYING THE SECOND FRACTION BY 2/2 WE GET 13X/30-8X/30 OR (13X-8X)/30 OR 5X/30 OR X/6
