Question

Answer 1

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

\(\dfrac{3}{4}-\dfrac{1}{4}:x=-\dfrac{5}{3}\)

        \(\dfrac{1}{4}:x=\dfrac{3}{4}-\left(-\dfrac{5}{3}\right)\)

         \(\dfrac{1}{4}:x=\dfrac{29}{12}\)

               \(x=\dfrac{1}{4}:\dfrac{29}{12}\) 

               \(x=\dfrac{3}{29}\)

Answer 2

c, 3/4 - 1/4 : x = -5/3

1/4 : x = 3/4 - (-5)/3

1/4 : x = 29/12

x = 1/4 : 29/12 

x = 3/29 

vậy x =...
