\n" ); document.write( "-------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "dex + dex = dex
\n" ); document.write( "-----
\n" ); document.write( "0.7x + 0.1*500 = 0.45(x+500)
\n" ); document.write( "------
\n" ); document.write( "70x + 10*500 = 45x + 45*500
\n" ); document.write( "-----------------------------
\n" ); document.write( "25x = 35*500
\n" ); document.write( "x = (7/5)(500)
\n" ); document.write( "x = 700 ml (amt. of 70% solution needed)
\n" ); document.write( "================================
