Do it like this one:
\n" ); document.write( " =========================================
\n" ); document.write( " A large solar heating panel requires 110 gallons of a fluid that is 40% antifreeze. The fluid comes in either a 65% solution or a 20% solution. How many gallons of each should be used to prepare the 110-gallon solution?
\n" ); document.write( " ====================
\n" ); document.write( " s = amount of 65%
\n" ); document.write( " t = amount of 20%
\n" ); document.write( " ----
\n" ); document.write( " s + t = 111 (total solution)
\n" ); document.write( " 65s + 20t = 40*110 (total antifreeze)
\n" ); document.write( "
\n" );
