Let $\"f\"$ = price of one front row ticket
\n" ); document.write( "Let $\"t\"$ = price of one lawn ticket
\n" ); document.write( " $\"f+=+2t+-+4\"$
\n" ); document.write( " $\"2f+%2B+5t+=+100\"$
\n" ); document.write( "multiply the 1st equation by -2 and add to the 2nd
\n" ); document.write( " $\"-2f+=+-4t+%2B+8\"$
\n" ); document.write( " $\"2f+=+-5t+%2B+100\"$
\n" ); document.write( " $\"0+=+-9t+%2B+108\"$
\n" ); document.write( "Add $\"9t\"$ to both sides
\n" ); document.write( " $\"9t+=+108\"$
\n" ); document.write( " $\"t+=+12\"$
\n" ); document.write( " $\"f+=+2t+-+4\"$
\n" ); document.write( " $\"f+=+2%2A12+-+4\"$
\n" ); document.write( " $\"f+=+20\"$
\n" ); document.write( "The cost of a front row ticket is $20
\n" ); document.write( "The cost of a lawn ticket is $12
\n" ); document.write( "check:
\n" ); document.write( " $\"2f+%2B+5t+=+100\"$
\n" ); document.write( " $\"2%2A20+%2B+5%2A12+=+100\"$
\n" ); document.write( " $\"40+%2B+60+=+100\"$
\n" ); document.write( " $\"100+=+100\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
