\n" ); document.write( "Add the equations,
\n" ); document.write( "\"A%2BB%2BA-B=117%2B21\"
\n" ); document.write( "\"2A=138\"
\n" ); document.write( "\"A=69\"
\n" ); document.write( "Now use either equation to solve for \"B\"
\n" ); document.write( "\"B=117-A\"
\n" ); document.write( "\"B=117-69\"
\n" ); document.write( "\"B=48\"
