45*.15+.35X=.25(45+X)
\n" ); document.write( "6.75+.35X=11.25+.25X
\n" ); document.write( ".35X-.25X=11.25-6.75
\n" ); document.write( ".1X=4.5
\n" ); document.write( "X=4.5/.1
\n" ); document.write( "X=45 ML OF 35% NEEDS TO BE ADDED.
\n" ); document.write( "PROOF:
\n" ); document.write( "45*.15+.35*45=.25(45+45)
\n" ); document.write( "6.75+15.75=.25*90
\n" ); document.write( "22.5=22.5
\n" ); document.write( "
