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

Answer 4

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

Answer 5

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