x = adult
\n" ); document.write( "y = children's
\n" ); document.write( "7x+5y=104
\n" ); document.write( "any multiple of 5 will end with 0 or 5
\n" ); document.write( "subtract multiples of 7 from 104 until getting an integer ending in 0 or 5
\n" ); document.write( "x could be 2 or 7 or 12
\n" ); document.write( "7(2) + 5y = 104
\n" ); document.write( "14 + 5y = 104
\n" ); document.write( "5y = 90
\n" ); document.write( "y = 18
\n" ); document.write( "2 adults, 18 children's
\n" ); document.write( "OR
\n" ); document.write( "7(7) + 5y = 104
\n" ); document.write( "49 + 5y = 104
\n" ); document.write( "5y = 55
\n" ); document.write( "y = 11
\n" ); document.write( "7 adults, 11 children's
\n" ); document.write( "OR
\n" ); document.write( "7(12)+ 5y = 104
\n" ); document.write( "84 + 5y = 104
\n" ); document.write( "5y = 20
\n" ); document.write( "y = 4
\n" ); document.write( "12 adults, 4 children's
