Let $\"A\"$ and $\"B\"$ be the integers.
\n" ); document.write( "1. $\"A%2BB=20\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "2. $\"5A=2%2B2B\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( " $\"2A%2B2B=40\"$
\n" ); document.write( "From eq. 2,
\n" ); document.write( " $\"2B=5A-2\"$
\n" ); document.write( "Substitute into eq. 1,
\n" ); document.write( " $\"2A%2B%285A-2%29=40\"$
\n" ); document.write( " $\"7A=42\"$
\n" ); document.write( " $\"highlight%28A=6%29\"$
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( " $\"6%2BB=20\"$
\n" ); document.write( " $\"highlight%28B=14%29\"$ \n" ); document.write( "

\n" );
