.20x+.14(15-x)=.16*15
\n" ); document.write( ".20x+2.1-.14x=2.4
\n" ); document.write( ".06x=2.4-2.1
\n" ); document.write( ".06x=.3
\n" ); document.write( "x=.3/.06
\n" ); document.write( "x=5 gal. of 20% solution is used.
\n" ); document.write( "15-5=10 gal. or 14% solution is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".20*5+.14*10=.16*15
\n" ); document.write( "1+1.4=2.4
\n" ); document.write( "2.4=2.4
\n" ); document.write( "
