walnuts' weight = W pounds
\n" ); document.write( "pecans' weight = (10 - W) pounds\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%2AW+%2B+5%2A%2810+-+W%29+=+10%2A3.7\"
\n" ); document.write( "3W + 50 - 5W = 37
\n" ); document.write( "50 - 37 = 5W - 3W
\n" ); document.write( "13 = 2W
\n" ); document.write( "W = 13/2 = 6.5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, walnuts weight should be 6.5 pounds and pecans' weight should be (10 - 6.5) = 3.5 pounds
\n" ); document.write( "
\n" );
