bn nên vào Giúp tôi giải tiếng anh để hỏi ý còn ở đây là Toán tiếng Việt

Mk thấy không hẳn là thế, ở đây rất nhiều các bạn hỏi các câu hỏi bằng toán Tiếng Việt mà, Toán tiếng Anh hay toán Tiếng Việt thì đều là toán chứ ?

Gọi giá tiền của 1 cái bàn là x(đô la), giá tiền của 1 cái ghế là y(đô la)

1 cái bàn và 3 cái ghế giống nhau có giá 765 đô la nên x+3y=765(1)

2 cái bàn và 4 cái ghế như vậy có giá 1370 đô la nên 

2x+4y=1370

=>x+2y=685(2)

Từ (1),(2) ta có hệ phương trình:

\(\left\{{}\begin{matrix}x+3y=765\\x+2y=685\end{matrix}\right.\)

=>\(\left\{{}\begin{matrix}x+3y-x-2y=765-685\\x+2y=685\end{matrix}\right.\)

=>\(\left\{{}\begin{matrix}y=80\\x=685-2y=685-160=525\end{matrix}\right.\left(nhận\right)\)

=>Giá tiền của 8 cái ghế là 8*80=640 đô la

If there is 1 person tell truth, it will be right. Because the other wil say that, 1 people tell the truth is among of each person's neighbors,exepct the person tell the truth. But if 2 or more, it will be wrong. Because there are 13 neighbors, if there are 2 or more tell the truth, number people tell the truth is increase among of each person neighbors.

So there are 13 people are liars.
