Let $\"+c+\"$ = number of children
\n" ); document.write( "Let $\"+a+\"$ = number of adults
\n" ); document.write( "given:
\n" ); document.write( " $\"+a+%2B+c+=+68+\"$
\n" ); document.write( " $\"+c+=+3a+\"$
\n" ); document.write( "---------
\n" ); document.write( " $\"+a+=+c%2F3+\"$
\n" ); document.write( " $\"+c%2F3+%2B+c+=+68+\"$
\n" ); document.write( " $\"+c+%2B+3c+=+204+\"$
\n" ); document.write( " $\"+4c+=+204+\"$
\n" ); document.write( " $\"+c+=+51+\"$
\n" ); document.write( "There are 51 children
\n" ); document.write( "check:
\n" ); document.write( " $\"+a+%2B+c+=+68+\"$
\n" ); document.write( " $\"+a+%2B+51+=+68+\"$
\n" ); document.write( " $\"+a+=+17+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+c+=+3a+\"$
\n" ); document.write( " $\"+51+=+3%2A17+\"$
\n" ); document.write( " $\"+51+=+51+\"$
