Tìm x bt

a.x- 4/9=-1/2

b. x-5/6=-7/3

Answer 1

a) \(x-\dfrac{4}{9}=\dfrac{-1}{2}=>x=\dfrac{-1}{2}+\dfrac{4}{9}=>x=\dfrac{-9}{18}+\dfrac{8}{18}=>x=-\dfrac{1}{18}\)

b) \(x-\dfrac{5}{6}=-\dfrac{7}{3}=>x=\dfrac{-7}{3}+\dfrac{5}{6}=>x=-\dfrac{14}{6}+\dfrac{5}{6}=>x=-\dfrac{3}{2}\)

Answer 2

\(a,x-\dfrac{4}{9}=\dfrac{-1}{2}\)

\(\Rightarrow x=\dfrac{-1}{2}+\dfrac{4}{9}\)

\(\Rightarrow x=\dfrac{-1}{18}\)

\(b,x-\dfrac{5}{6}=\dfrac{-7}{3}\)

\(\Rightarrow x=\dfrac{-7}{3}+\dfrac{5}{6}\)

\(\Rightarrow x=\dfrac{-3}{2}\)
