.60x+.10*15=.20(15+x)
\n" ); document.write( ".60x+1.5=3+.20x
\n" ); document.write( ".60x-.20x=3-1.5
\n" ); document.write( ".40x=1.5
\n" ); document.write( "x=1.5/.4
\n" ); document.write( "x=3.75 liters of 60% solution is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".60*3.75+.10*15=.20(15+3.75)
\n" ); document.write( "2.25+1.5=.20*18.75
\n" ); document.write( "3.75=3.75\r
