Let $\"A\"$ and $\"B\"$ be the unknown lengths,
\n" ); document.write( " $\"A%2BB%2B12=34\"$
\n" ); document.write( " $\"A=4B-3\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"4B-3%2BB%2B12=34\"$
\n" ); document.write( " $\"5B%2B9=34\"$
\n" ); document.write( " $\"5B=25\"$
\n" ); document.write( " $\"highlight%28B=5%29\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"A=4%285%29-3\"$
\n" ); document.write( " $\"A=20-3\"$
\n" ); document.write( " $\"highlight%28A=17%29\"$
\n" ); document.write( " \n" ); document.write( "
