\n" ); document.write( ".
\n" ); document.write( "simplify and solve
\n" ); document.write( ".04x - .01x + .01*15 = .02*15gal
\n" ); document.write( ".
\n" ); document.write( ".03x = .01*15gal
\n" ); document.write( ".
\n" ); document.write( "x = .15/.03
\n" ); document.write( ".
\n" ); document.write( "x = 5 gal
\n" ); document.write( ".
