You can put this solution on YOUR website!
Let x=number of quarts of water to be added\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The amount of pure alcohol before adding water = amount of pure alcohol after adding water. So our equation to solve is:\r
\n" ); document.write( "\n" ); document.write( "6(.60)=(6+x)(.40) clear parens\r
\n" ); document.write( "\n" ); document.write( "3.60=2.40+.4x subtract 2.40 from both sides\r
\n" ); document.write( "\n" ); document.write( "3.60-2.40=2.40-2.40+.40x
\n" ); document.write( "1.20=.40x
