\n" ); document.write( "------------------------------
\n" ); document.write( "value + value = value
\n" ); document.write( "2.40t + 3.40z = 3*2
\n" ); document.write( "t + z = 2
\n" ); document.write( "-------------------------
\n" ); document.write( "Simplify:
\n" ); document.write( "240t + 340z = 600
\n" ); document.write( "240t + 240z = 480
\n" ); document.write( "----------------------
\n" ); document.write( "Subtract 2nd from 1st to get:
\n" ); document.write( "100z = 120
\n" ); document.write( "z = (6/5) lbs (amt. of pretzels in the mix)
\n" ); document.write( "---------
\n" ); document.write( "Since t + z = 2
\n" ); document.write( "t+(6/5) = (10/5)t = 4/5 lbs (amt. of potato chips)
\n" ); document.write( "----------------------
