suy ra:
\(\dfrac{4\left(3x-2y\right)}{16}=\dfrac{3\left(2z-4x\right)}{9}=\dfrac{2\left(4y-3z\right)}{4}\)
\(=\dfrac{12x-8y+6z-12x+8y-6z}{29}=0\)
Vậy
\(\dfrac{3x-2y}{4}=0\Rightarrow3x=\dfrac{2y\Rightarrow x}{2}=\dfrac{y}{3}\left(1\right)\)
\(\dfrac{2z-4x}{4}=0\Rightarrow2z=4x\Rightarrow\dfrac{x}{2}=\dfrac{z}{4}\left(2\right)\)
từ (1) và (2) ta được\(\dfrac{x}{2}=\dfrac{y}{3}=\dfrac{z}{4}\)
