Question

Tìm x, biết:

\(\dfrac{1}{2019}:2017.x\) = \(-\dfrac{1}{2017}\)

Answer 1

\(\dfrac{1}{2019}:2017.x=-\dfrac{1}{2017}\)

\(\dfrac{1}{2019.2017}x=-\dfrac{1}{2017}\)

x=\(-\dfrac{1}{2017}:\dfrac{1}{2019.2017}\)=-2019

Vậy x=-2019

Answer 2

2017 . x = \(\dfrac{1}{2019}:\left(\dfrac{-1}{2017}\right)\)

2017 . x = \(\dfrac{1}{2019}.\left(-2017\right)\)

2017 . x = \(-\dfrac{2017}{2019}\)

x = \(-\dfrac{2017}{2019}:2017\)

x = \(-\dfrac{2017}{2019}.\dfrac{1}{2017}\)

x = \(\dfrac{-1}{2019}\)
