Question

tìm các số nguyên x,y,z,t biết:

-3/6=x/-2=-18/y=-z/24

x/y=2/5

x/-3=4/y

-7/6=x/18=-14/z=t/102

Answer 1

1)\(\dfrac{-3}{6}=\dfrac{x}{-2}=\dfrac{-18}{y}=\dfrac{-z}{24}\)

\(\Rightarrow x=-\dfrac{3}{6}\cdot\left(-2\right)=1\)

\(\Rightarrow y=-18:\dfrac{-3}{6}=36\)

\(\Rightarrow z=-\dfrac{3}{6}\cdot\left(-24\right)=12\)

Answer 2

1)\(\dfrac{-3}{6}=\dfrac{x}{-2}=\dfrac{-18}{y}=\dfrac{-z}{24}\)

\(\Rightarrow x=-\dfrac{3}{6}\cdot\left(-2\right)=1\)

\(\Rightarrow y=-18:\dfrac{-3}{6}=36\)

\(\Rightarrow z=-\dfrac{3}{6}\cdot\left(-24\right)=12\)

Answer 3

1)\(\dfrac{-3}{6}=\dfrac{x}{-2}=\dfrac{-18}{y}=\dfrac{-z}{24}\)

\(\Rightarrow x=-\dfrac{3}{6}\cdot\left(-2\right)=1\)

\(\Rightarrow y=-18:\dfrac{-3}{6}=36\)

\(\Rightarrow z=-\dfrac{3}{6}\cdot\left(-24\right)=12\)
2) \(\dfrac{x}{y}=\dfrac{2}{5}\Rightarrow\left\{{}\begin{matrix}x=2\\y=5\end{matrix}\right.\)

3) \(\dfrac{x}{-3}=\dfrac{4}{y}\Rightarrow\left\{{}\begin{matrix}x=4\\y=-3\end{matrix}\right.\)
