cop thì ghi tham khảo cái đi bạn :)) có lòng tự trọng xíu

Gọi \(x,y\left(l\right)\) lần lượt là số lít cồn \(90^0\) và \(60^0\) \(\left(x,y\in N\circledast\right)\)

Vì cô Phương và nhóm bạn đã pha được tổng cộng 6l cồn nên:

\(x+y=6\left(1\right)\)

Vì cô Phương và nhóm bạn pha được 6l cồn \(70^0\) từ cồn \(90^0\) và \(60^0\), nên:

\(90x+60y=6\cdot70\left(2\right)\)

Từ (1) và (2), ta có hpt: \(\left\{{}\begin{matrix}x+y=6\\90x+60y=2\cdot70\end{matrix}\right.\)\(\Leftrightarrow\left\{{}\begin{matrix}x=2\left(n\right)\\y=4\left(n\right)\end{matrix}\right.\)
