\n" ); document.write( "19% alcohol solution : x ml
\n" ); document.write( "10% alcohol solution 50 ml
\n" ); document.write( "15% alcohol solution : x+50 ml
\n" ); document.write( "...
\n" ); document.write( "0.19x+0.1*50=0.15(x+50)
\n" ); document.write( "0.19x+5=0.15x+7.5
\n" ); document.write( "0.19x-0.15x=7.5-5
\n" ); document.write( "0.04x = 2.5
\n" ); document.write( "x=2.5/0.04
\n" ); document.write( "= 62.5 ml of 19%
