\n" ); document.write( "--------------------
\n" ); document.write( "Solving with one variable:
\n" ); document.write( "Value EQUATION: 7.5x + 3(113-x) = 663
\n" ); document.write( "7.5x + 339 - 3x = 663
\n" ); document.write( "4.5x = 324
\n" ); document.write( "x = 72 (number of adult tickets sold)
\n" ); document.write( "113-x = 113-73 = 41 (number of child tickets sold)
\n" ); document.write( "===================================================
