\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "alc + alc = alc
\n" ); document.write( "0.20x + 0.15*2 = 0.18(x+2)
\n" ); document.write( "-----
\n" ); document.write( "20x + 15*2 = 18x + 18*2
\n" ); document.write( "2x = 3*2
\n" ); document.write( "x = 3 gallons (amt. of 20% solution needed)
