Let \"+x+\" = pounds of cashews to be used
\n" ); document.write( "\"+6x+\" = cost of cashews used
\n" ); document.write( "\"+3%2A12+=+36+\" = cost of peanuts used
\n" ); document.write( "---------------
\n" ); document.write( "\"+%28+6x+%2B+36+%29+%2F+%28+x+%2B+12+%29+=+4.2+\"
\n" ); document.write( "\"+6x+%2B+36+=+4.2%2A%28+x+%2B+12+%29+\"
\n" ); document.write( "\"+6x+%2B+36+=+4.2x+%2B+50.4+\"
\n" ); document.write( "\"+1.8x+=+14.4+\"
\n" ); document.write( "\"+x+=+8+\"
\n" ); document.write( "8 pounds of cashews should be used
