From eq. 1,
\n" ); document.write( " $\"x=33-7y\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"3x=99-21y\"$
\n" ); document.write( "Substitute into eq. 2,
\n" ); document.write( " $\"99-21y-2y=7\"$
\n" ); document.write( " $\"-23y=-92\"$
\n" ); document.write( " $\"y=4\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"x=33-7%284%29\"$
\n" ); document.write( " $\"x=33-28\"$
\n" ); document.write( " $\"x=5\"$
\n" ); document.write( "(5,4) \n" ); document.write( "

\n" );
