.12x+.06(240-x)=.07*240
\n" ); document.write( ".12x+14.4-.06x=16.8
\n" ); document.write( ".06x=16.8-14,4
\n" ); document.write( ".06x=2.4
\n" ); document.write( "x=2.4/.06
\n" ); document.write( "x=40 pounds of soybeans was used.
\n" ); document.write( "240-40=200 pounds of cornmeal was used.
\n" ); document.write( "Proof:
\n" ); document.write( ".12*40+.06*200=16.8
\n" ); document.write( "4.8+12=16.8
\n" ); document.write( "16.8=16.8
