I'm trying to figure out how many lbs of corn meal & soy bean there are in the mixture

Oh, you solve one eq for x or y, then put it in the other. The x is soybean, y cornmeal.

anonymous · Answer

$$.16x+.08(320-x)=.14\times 320=44.8$$
$$.16x+25.6-.08x=44.8$$
$$.08x+25.6=44.8$$
$$.08x=19.2$$
$$x=\frac{19.2}{.08}=240$$
