Let x = the number of pints of water to be mixed with the 3 pints of 90% developer to obtain (3+x) pints of the 17% developer mixture.
\n" ); document.write( "3(0.9) = (3+x))(0.17) Simplify.
\n" ); document.write( "2.7 = 0.51+0.17x Subtract 0.51 from both sides.
\n" ); document.write( "2.19 = 0.17x Divide both sides by 0.17
\n" ); document.write( "12.8824 = x
\n" ); document.write( "Yuo need to mix 12.9 pints of water with the 3 pints of 90% developer mixture to obtain (12.9+3 = 15.9) pints of 17% developer mixture. \n" ); document.write( "

\n" );
