A chemist has two solutions. one has 40% the other 25% concentrate. how many liters of each solution must be mixed to obtain 129liters of 34% solution??

\n" ); document.write( "\n" ); document.write( "..\r
\n" ); document.write( "\n" ); document.write( "let x=liters of 40% concentrate
\n" ); document.write( "then 129-x = liters of 25% concentrate\r
\n" ); document.write( "\n" ); document.write( ".4x+.25(129-x)=.34(129)
\n" ); document.write( ".4x+.25(129)-.25x=.34(129)
\n" ); document.write( ".15x=.34(129)-.25(129)
\n" ); document.write( ".15x=129(.34-.25)
\n" ); document.write( "x=129(.09)/.15
\n" ); document.write( "x=77.4 liters
\n" ); document.write( "129-x=129-77.4=51.6 liters\r
\n" ); document.write( "\n" ); document.write( "ans: 77.4 liters of the 40% concentrate and 51.6 liters of the 25% concentrate must be mixed to obtain 129 liters of 34% solution. \n" ); document.write( "
\n" );
