let there are x adults & y children
\n" ); document.write( "then x+y=175
\n" ); document.write( "or x=175-y........1
\n" ); document.write( "cost of tickets is $6 for adults and $2 for children
\n" ); document.write( "then 6x+2y=750........2
\n" ); document.write( "putting the value from 1
\n" ); document.write( "6(175-y)+2y=750
\n" ); document.write( "or 1050-6y+2y=750
\n" ); document.write( "or 4y=300
\n" ); document.write( "or y=75
\n" ); document.write( "from x=175-75-100
\n" ); document.write( "100 children tickets were sold
