You can put this solution on YOUR website!
To add/subtract fractions, you must have the same denominator. In this case, you need to find a common denominator. The LCD is 18 and the fractions change to $\"-2expr%2816%2F18%29\"$ and $\"2expr%2815%2F18%29\"$ . So your answer is $\"-1%2F18\"$ . \n" ); document.write( "
