Well, your answer is correct, so you can check it by substituting x =7 into the original equation and see if the two sides are equal.
\n" ); document.write( " $\"%284%2F%28x%2B5%29%29%2B%282%2F%28x-5%29%29+=+32%2F%28x%2B5%29%28x-5%29\"$ Substitute x = 7.
\n" ); document.write( " $\"%284%2F%287%2B5%29%29%2B%282%2F%287-5%29%29+=+32%2F%287%2B5%29%287-5%29\"$ Evaluate.
\n" ); document.write( " $\"%284%2F12%29%2B%282%2F2%29+=+32%2F%2812%29%2A%282%29\"$
\n" ); document.write( " $\"%284%2F12%29%2B%2812%2F12%29+=+32%2F24\"$ Multiply the left side by $\"2%2F2\"$ .
\n" ); document.write( " $\"%288%2F24%29%2B%2824%2F24%29+=+32%2F24\"$ Add the fractions on the left.
\n" ); document.write( " $\"32%2F24+=+32%2F24\"$ \n" ); document.write( "

\n" );
