Let $\"+a+\"$ = number of bottles of red wine sold
\n" ); document.write( "Let $\"+b+\"$ = number of bottles of white wine sold
\n" ); document.write( "-----------------
\n" ); document.write( "(1) $\"+a+%2B+b+=+40+\"$
\n" ); document.write( "(2) $\"+39.95a+%2B+30.49b+=+1456.1+\"$
\n" ); document.write( "--------------------------------
\n" ); document.write( "Multiply both sides of (1) by $\"+30.49+\"$
\n" ); document.write( "and subtract (1) from (2)
\n" ); document.write( "(2) $\"+39.95a+%2B+30.49b+=+1456.1+\"$
\n" ); document.write( "(1) $\"+-30.49a+-+30.49b+=+-1219.6+\"$
\n" ); document.write( "---------------------------------
\n" ); document.write( " $\"+9.46a+=+236.5+\"$
\n" ); document.write( " $\"+a+=+25+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+a+%2B+b+=+40+\"$
\n" ); document.write( "(1) $\"+b+=+15+\"$
\n" ); document.write( "25 bottles of red and 15 bottles of white were sold
\n" ); document.write( " \n" ); document.write( "

\n" );
