5x+3.8(10-x)=40 x being the kg amount of raisons.
\n" ); document.write( "5x+38-3.8x=40
\n" ); document.write( "5x-3.8x+38=40
\n" ); document.write( "1.2x=40-38
\n" ); document.write( "1.2x=2
\n" ); document.write( "x=2/1.2
\n" ); document.write( "x=1 2/3kg multiply this by 5=8 1/3 kg of raisons
\n" ); document.write( "10-x=8 1/3kg multiplied by 3.8=31 2/3 kg of peanuts
\n" ); document.write( "8 1/3+31 2/3= 40. \r
