x is an adults ticket
\n" ); document.write( "y is a child's ticket\r
\n" ); document.write( "\n" ); document.write( " x + y = 95 .....1
\n" ); document.write( "12x + 9y = 960 ....2\r
\n" ); document.write( "\n" ); document.write( "Multiply (1) by 9\r
\n" ); document.write( "\n" ); document.write( " 9x + 9y = 855 ....3
\n" ); document.write( "12x + 9y = 960 ....2\r
\n" ); document.write( "\n" ); document.write( "Subtract 3 from 2\r
\n" ); document.write( "\n" ); document.write( " 3x = 105
\n" ); document.write( " x = 35
\n" ); document.write( "Substitute x = 35 into (1)\r
\n" ); document.write( "\n" ); document.write( " x + y = 95
\n" ); document.write( "35 + y = 95
\n" ); document.write( " y = 95 - 35
\n" ); document.write( " y = 60\r
\n" ); document.write( "\n" ); document.write( " 35*$12 + 60*$9 = $960\r
\n" ); document.write( "\n" ); document.write( "Hope this helps
