mình có một câu hỏi ở ngữ văn đó

trả lời giúp mình đi mình sắp kiểm tra rồi

Please!!!!!!!!!!!!!!!!!!!

nhân từng hạng tử của giả thiết với 2 rồi cộng và trừ từng cái một là ra còn gì nx

Trình bày dài lắm

Ta có : \(\frac{x}{a+2b+c}=\frac{y}{2a+b-c}=\frac{z}{4a-4b+c}\)

=> \(\frac{a+2b+c}{x}=\frac{2a+b-c}{y}=\frac{4a-4b+c}{z}\)

=> \(\frac{a+2b+c}{x}=\frac{2\left(2a+b-c\right)}{2y}=\frac{4a-4b+c}{z}=\frac{a}{x+2y+z}\)(1)

=> \(\frac{2\left(a+2b+c\right)}{2x}=\frac{2a+b-c}{y}=\frac{4a+4b+c}{z}=\frac{b}{2x+y-z}\)(2)

=> \(\frac{4\left(a+2b+c\right)}{4x}=\frac{4\left(2a+b-c\right)}{4y}=\frac{4a-4b+c}{z}=\frac{c}{4x-4y+z}\)(3)

Từ (1);(2);(3) suy ra \(\frac{a}{x+2y+z}=\frac{b}{2x+y-z}=\frac{c}{4x-4b+z}\)

easy!\(\frac{x}{a+2b+c}=\frac{y}{2a+b-c}=\frac{z}{4a-4b+c}=\frac{2y}{4a+2b-2c}=\frac{x+2y+z}{a+2b+c+4a+2b-2c+4a-4b+c}\)

\(=\frac{x+2y+z}{9a}\left(1\right)\)

\(=\frac{2x}{2a+4b+2c}=\frac{2x+y-z}{2a+4b+2c+2a+b-c-4a+4b-c}=\frac{2x+y-z}{9b}\left(2\right)\)

\(=\frac{4x}{4a+8b+4c}=\frac{4y}{8a+4b-4c}=\frac{4x-4y+z}{4a+8b+4c-8a-4b+4c+4a-4b+c}=\frac{4x-4y+z}{9c}\left(3\right)\)

Từ (1),(2),(3) ta được:\(\frac{x+2y+z}{9a}=\frac{2x+y-z}{9b}=\frac{4x-4y+z}{9c}\)

\(\Rightarrow\frac{x+2y+z}{a}=\frac{2x+y-z}{b}=\frac{4x-4y+z}{c}\)

\(\Rightarrow\frac{a}{x+2y+z}=\frac{b}{2x+y-z}=\frac{c}{4x-4y+z}\left(đpcm\right)\)

Hello, I am Hoang Anh ! And you ?

Yeah ! I am Chau, 11 Years old, I am a student at class 6D1.

Gọi giá của 1 cái bàn và 1 cái ghế lần lượt là a(đô la) và b(đô la)

(Điều kiện: a>0 và b>0)

Giá của 1 cái bàn và 3 cái ghế là 765 đô la nên ta có: a+3b=765(1)

Giá của 2 cái bàn và 4 cái ghế là 1370 đô la nên ta có:

2a+4b=1370

=>a+2b=685(2)

Từ (1) và (2) ta có hệ phương trình:

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

=>\(\left\{{}\begin{matrix}a+3b-a-2b=80\\a+2b=685\end{matrix}\right.\)

=>\(\left\{{}\begin{matrix}b=80\\a=525\end{matrix}\right.\)

Giá của 8 cái ghế là 80*8=640 đô la
