.08*2000=.06(2000+x)
\n" ); document.write( "160=120+.06x
\n" ); document.write( "-.06x=120-160
\n" ); document.write( "-.06x=-40
\n" ); document.write( "x=-40/-.06
\n" ); document.write( "x=666.56 gal. of gas with no ethanol.
\n" ); document.write( "Proof:
\n" ); document.write( ".08*200=.06(2000+666.67)
\n" ); document.write( "160=.06*2666.67
\n" ); document.write( "160~160
