Let A be the amount of soybeans, B the amount of cornmeal.
\n" ); document.write( "Write an equation for the total weight of the mixture.
\n" ); document.write( "1.\"A%2BB=360\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Write an equation for the total protein content of the mixture.
\n" ); document.write( "\"18A%2B9B=11%28360%29\"
\n" ); document.write( "2.\"2A%2BB=440\"
\n" ); document.write( "Subtract eq. 1 from eq. 2,
\n" ); document.write( "\"2A%2BB-A-B=440-360\"
\n" ); document.write( "\"highlight%28A=80%29\"
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( "\"80%2BB=360\"
\n" ); document.write( "\"highlight%28B=280%29\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Use 80 lbs of soybeans, 280 lbs of cornmeal.
\n" ); document.write( "
\n" ); document.write( "
