Let A be the amount of 14% alcohol solution, B the amount of 22% solution.
\n" ); document.write( "1.\"A%2BB=200\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"14A%2B22B=17.6%28200%29\"
\n" ); document.write( "2.\"7A%2B11B=1760\"\r
\n" ); document.write( "\n" ); document.write( "Multiply eq. 1 by (-7) and add to eq. 2,
\n" ); document.write( "\"-7A-7B%2B7A%2B11B=-1400%2B1760\"
\n" ); document.write( "\"4B=360\"
\n" ); document.write( "\"highlight%28B=90%29\"ml
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( "\"A%2B90=200\"
\n" ); document.write( "\"highlight%28A=110%29\"ml
