Let's put
\n" ); document.write( "chairs: c
\n" ); document.write( "tables: t\r
\n" ); document.write( "\n" ); document.write( " $\"3%2Ac%2B1%2At=900\"$
\n" ); document.write( " so
\n" ); document.write( " $\"t=900-3%2Ac\"$
\n" ); document.write( " $\"5%2Ac%2B3%2At=2100\"$
\n" ); document.write( "By substituting t from the above equation, we get:
\n" ); document.write( " $\"5%2Ac%2B3%2A%28900-3%2Ac%29=2100\"$
\n" ); document.write( " $\"5%2Ac%2B2700-9%2Ac=2100\"$
\n" ); document.write( " $\"2700-2100=9%2Ac-5%2Ac\"$
\n" ); document.write( " $\"600=4%2Ac\"$
\n" ); document.write( " $\"c=150\"$ \r
\n" ); document.write( "\n" ); document.write( "So
\n" ); document.write( " $\"t=900-3%2A150=450\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"4%2Ac%2Bt=4%2A150%2B450=1050\"$ \n" ); document.write( "

\n" );
