Question

Tìm x biết:

\(\dfrac{3}{4}+\dfrac{1}{4}\div x=-2\)

 

Answer 1

`3/4 + 1/4 :x = -2`

`1/4 : x = -2 - 3/4`

`1/4 : x= -11/4`

`x= 1/4 : (-11)/4`

`x= 1/4 . (-4)/11`

`x= -1/11`

Answer 2

`3/4 + 1/4 : x = -2`

`1/4 : x = -2 - 3/4`

`1/4 : x = -11/4`

`x = 1/4 : (-11/4)`

` x = 1/4 xx (-4/11)`

`x = -1/11`

Answer 3

\(\Leftrightarrow\dfrac{1}{4}:x=-2-\dfrac{3}{4}=-\dfrac{11}{4}\\ \Leftrightarrow x=\dfrac{1}{4}:-\dfrac{11}{4}=-\dfrac{1}{11}\)

Answer 4

`=> 1/4 : x = -2 - 3/4`

`=> 1/4 : x = -11/4`

`=> x = 1/4 : -11/4`

`=> x = -1/11`
