\n" ); document.write( "Equation:
\n" ); document.write( "alcohol + alcohol = alcohol
\n" ); document.write( "0.35x + 0.25*12 = 0.26(x+12)
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "35x + 25*12 = 26x + 26*12
\n" ); document.write( "9x = 12
\n" ); document.write( "x = 4/3 liter (amt. of 35% solution needed in the mixture)
