x + y = 320........(1)
\n" ); document.write( "5x + 2y = 1255.....(2)\r
\n" ); document.write( "\n" ); document.write( "Multiply (1) by 2\r
\n" ); document.write( "\n" ); document.write( "2x + 2y = 640
\n" ); document.write( "5x + 2y = 1255\r
\n" ); document.write( "\n" ); document.write( "Subtract \r
\n" ); document.write( "\n" ); document.write( "-3x = -615
\n" ); document.write( " x = 205
\n" ); document.write( "Substitute x =205 in (1)
\n" ); document.write( "205 + y = 320
\n" ); document.write( " y = 320 - 205
\n" ); document.write( " y = 115
\n" ); document.write( "So he sold 205 Adult tickets
\n" ); document.write( "and 115 Children's tickets\r
\n" ); document.write( "\n" ); document.write( "
