A+C=23 OR A=23-C FOR THE NUMBER OF TICKETS SOLD.
\n" ); document.write( "11A+10C=246
\n" ); document.write( "NOW REPLACE A WITH(23-C) IN THE SECOND EQUATION & SOLVE FOR C
\n" ); document.write( "11(23-C)+10C=246
\n" ); document.write( "253-11C+10C=246
\n" ); document.write( "-C=246-253
\n" ); document.write( "-C=-7
\n" ); document.write( "C=7 CHILDREN'S TICKETS WERE SOLD. (NO IDEA HOW MANY CHILDREN ATTENDED)
\n" ); document.write( "23-7=16 ADULT TICKETS SOLD.
\n" ); document.write( "PROOF
\n" ); document.write( "11*16+10*7=246
\n" ); document.write( "176+70=246
\n" ); document.write( "246=246
\n" ); document.write( "
