10.36 = -12.x
360=-12.x
x=360 : -12
x=-30
\(\dfrac{10}{x}=\dfrac{-12}{36}\)
:)10.36=x.(-12)
360=x.(-12)
:)x=360:(-12)
x=(-30)
\(\dfrac{10}{x}\) = -\(\dfrac{12}{36}\)
\(\Rightarrow\) \(\dfrac{10}{x}\) = - \(\dfrac{1}{3}\)
\(\Rightarrow\) 10 = - \(\dfrac{1}{3}\)x
\(\Rightarrow\) 10 = -\(\dfrac{x}{3}\)
\(\Rightarrow\) 10 . 3 = -x
\(\Rightarrow\) 30 = -x
\(\Rightarrow\) -30 = x
\(\Rightarrow\) x = -30
Vậy x = -30
10/x = -12/36
=)(-12).x=10.36
x=10.36/-12
x=360/-12
x=-30
Vậy:x=-30
\(\dfrac{10}{x}\)=\(\dfrac{-12}{36}\)
\(\dfrac{10}{x}\)=\(\dfrac{-1}{3}\)
x.(-1)=10.3
x.(-1)=30
x=30:(-1)
x= -30
