Từ \(10x=6y=7z\) \(\Rightarrow\hept{\begin{cases}10x=6y\\6y=7z\end{cases}}\)

Từ \(10x=6y\)\(\Rightarrow\)\(\frac{x}{6}=\frac{y}{10}=\frac{x}{6}.\frac{1}{7}=\frac{y}{10}.\frac{1}{7}=\frac{x}{42}=\frac{y}{70}\)( 1 )

Từ \(6y=7z\)\(\Rightarrow\)\(\frac{y}{7}=\frac{z}{6}=\frac{y}{7}.\frac{1}{10}=\frac{z}{6}.\frac{1}{10}=\frac{y}{70}=\frac{z}{60}\)( 2 )

Từ ( 1 ) và ( 2 ) suy ra : \(\frac{x}{42}=\frac{y}{70}=\frac{z}{60}\)

Áp dụng tính chất của dãy tỉ số bằng nhau ta có :

\(\frac{x}{42}=\frac{y}{70}=\frac{z}{60}=\frac{2x}{84}=\frac{7y}{490}=\frac{3z}{180}=\frac{2x-7y+3z}{84-490+180}=\frac{-11}{-226}=\frac{11}{226}\)

\(\Rightarrow\hept{\begin{cases}\frac{x}{42}=\frac{11}{226}\\\frac{y}{70}=\frac{11}{226}\\\frac{z}{60}=\frac{11}{226}\end{cases}}\)\(\Rightarrow\hept{\begin{cases}x=\frac{231}{113}\\y=\frac{385}{113}\\z=\frac{330}{113}\end{cases}}\)
