Question

-25  =  10

----      ----

x        -12

x=?

Answer 1

\(-\dfrac{25}{.x}=\dfrac{10}{-12}\)

\(\Leftrightarrow x=\dfrac{\left(-25\right)\cdot\left(-12\right)}{10}=30\)

Answer 2

\(\dfrac{-25}{x}\)=\(\dfrac{10}{-12}\)

=>(-25)*(-12)=x*10

      300         =x*10

=>x=300/10

=>x=30

vậy x=30

Answer 3

\(\dfrac{-25}{x}=\dfrac{10}{-12}\) 

\(\Rightarrow x=\dfrac{-25.-12}{10}=30\)
