Question

Tìm x

\(\frac{-2}{3}.x+\frac{13}{15}=\frac{7}{10}\)

Answer 1

\(-\frac{2}{3}\cdot x+\frac{13}{15}=\frac{7}{10}\)

\(-\frac{2}{3}\cdot x=\frac{7}{10}-\frac{13}{15}=-\frac{1}{6}\)

\(x=-\frac{1}{6}:\left(-\frac{2}{3}\right)=\frac{1}{4}\)

Answer 2

-2/3.x=7/10-13/5

-2/3.x=-1/6

      x=-1/6.(-3/2)

      x=-1/4

Answer 3

-2/3*X=7/10-13/15

 -2/3*x=-1/6

         x=(-1/6:-2/3

         x=1/4

Vậy x=1/4
