$\"2%2F%28r-5%29+%2B+3%2F%282r%2B1%29+=+22%2F%28%282r%2B1%29%28r-5%29%29\"$
\n" ); document.write( "

\n" ); document.write( "

\n" ); document.write( " $\"2%282r%2B1%29%2B3%28r-5%29=22\"$
\n" ); document.write( " $\"4r%2B2%2B3r-15=22\"$
\n" ); document.write( " $\"7r-13=22\"$
\n" ); document.write( " $\"7r=35\"$
\n" ); document.write( " $\"r=5\"$
\n" ); document.write( "However, in eliminating the denominators we assumed that $\"r-5%3C%3E0\"$ and $\"2r%2B1%3C%3E0\"$ to avoid division by zero.
\n" ); document.write( "So $\"r=5\"$ is not a possible solution.
\n" ); document.write( "No solution.
