Question

-2/3x + 1/5 = 1/3 x( -1/6 )

ai đúng mk tik cho nha

Answer 1

\(-\frac{2}{3}x+\frac{1}{5}=\frac{1}{3}\times\left(\frac{-1}{6}\right)\)

\(-\frac{2}{3}x+\frac{1}{5}=-\frac{1}{18}\)

\(-\frac{2}{3}x=-\frac{1}{18}-\frac{1}{5}\)

\(\frac{-2}{3}x=\frac{-5}{90}-\frac{18}{90}=-\frac{23}{90}\)

\(x=-\frac{23}{90}:\frac{-2}{3}\)

\(x=-\frac{23}{90}.\frac{3}{-2}=\frac{23}{60}\)

Vậy \(x=\frac{23}{60}\)
