\n" ); document.write( "Find the price of an adult's ticket and a child's ticket
\n" ); document.write( ":
\n" ); document.write( "Let x = cost of an adult ticket
\n" ); document.write( "then
\n" ); document.write( "(x-3) = cost of a child's ticket
\n" ); document.write( ";
\n" ); document.write( "9x + 2(x-3) = 192
\n" ); document.write( ":
\n" ); document.write( "9x + 2x - 6 = 192
\n" ); document.write( "11x = 192 + 6
\n" ); document.write( "11x = 198
\n" ); document.write( "x = $\"198%2F11\"$
\n" ); document.write( "x = $18 for an adult ticket
\n" ); document.write( "then
\n" ); document.write( "18 - 3 = $15 for a child's ticket
