Question

Answer 1

=>1/2:x=-2/3+5/6=1/6

=>x=1/2:1/6=1/2*6=3

Answer 2

\(\dfrac{1}{2}:x-\dfrac{5}{6}=-\dfrac{2}{3}\\ \Rightarrow\dfrac{1}{2}:x=-\dfrac{2}{3}+\dfrac{5}{6}=-\dfrac{4}{6}+\dfrac{5}{6}=\dfrac{1}{6}\\ \Rightarrow x=\dfrac{1}{2}:\dfrac{1}{6}=\dfrac{1}{2}.\dfrac{6}{1}=\dfrac{6}{2}=3\)

Vậy x = 3
