\n" );
document.write( "Hi,
\n" );
document.write( "Let x represent the amount of the 6% solution.  Then the final solution will be (20 + x)
\n" );
document.write( ".10*20gm + .06x = .08(20gm + x)
\n" );
document.write( "simplify and Solve
\n" );
document.write( ".10*20gm + .06x = .08*20gm + .08x\r
\n" );
document.write( "\n" );
document.write( ".10*20-.08*20 = .08x - .06x
\n" );
document.write( ".02*20 = .02x
\n" );
document.write( "20 = x
\n" );
document.write( "20 gm of 6% alcohol must be added to form an 8% alcohol
\n" );
document.write( "check your answer
\n" );
document.write( ".10*20 + .06*20 = .08*40  = 3.2 \n" );
