calculate ratios of two rice

https://math.stackexchange.com/questions/464545/calculate-ratios-of-two-rice

\begin{align} \dfrac{(2x+y)}{(5x+6y)} & =0.2 \\ \\ 2x + y & = 0.2(5x + 6y) \\ \\ x &= 1.2y - y = .2 y \\ \\ \dfrac xy &= .2 = \frac 15\end{align} So yes, the correct ratio is x:y = 1 \text{part 5-cent rice}:5 \text{parts 6-cent rice}

Basic algebra question. Find W in a system with 3 other unkowns and 2 equations.

https://math.stackexchange.com/questions/1722392/basic-algebra-question-find-w-in-a-system-with-3-other-unkowns-and-2-equations

Well, for example the second equation is satisfied by both (x,y,z)=(1,1,-2) and (x,y,z)=(0,1,-\frac{1}{2}) but both yield different results for W. So you need more information to find W. ...
