.18X+.03(15-X)=.08*15
\n" ); document.write( ".18X+.45-.03X=1.2
\n" ); document.write( ".15X=1.2-.45
\n" ); document.write( ".15X=.75
\n" ); document.write( "X=.75/.15
\n" ); document.write( "X=5 lITERS OF 18% SOLUTION IS USED.
\n" ); document.write( "15-5=10 lITERS OF 3% SOLUTION IS USED.
\n" ); document.write( "PROOF:
\n" ); document.write( ".18*5+.03*10=.08*15
\n" ); document.write( ".9+.3=1.2
\n" ); document.write( "1.2=1.2
