\n" ); document.write( "----------------
\n" ); document.write( "Equation:
\n" ); document.write( "silver + silver = silver
\n" ); document.write( "0.30x + 0.50*80 = 0.40(x+80)
\n" ); document.write( "-----
\n" ); document.write( "30x + 50*80 = 40x + 40*80
\n" ); document.write( "10x = 10*80
\n" ); document.write( "x = 80 liters (amt. of 30% alloy to add)
\n" ); document.write( "===================
