Add the equations together to eliminate \"y\".
\n" ); document.write( "\"x-y%2B2x%2By=5%2B1\"
\n" ); document.write( "\"3x=6\"
\n" ); document.write( "\"x=2\"
\n" ); document.write( "Then use either equation to solve for \"y\".
\n" ); document.write( "\"2-y=5\"
\n" ); document.write( "\"y=-3\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
