Question

Tìm x:

\(\frac{7}{5}+\frac{1}{5}.x=\frac{2}{15}\)

Answer 1

\(\frac{7}{5}+\frac{1}{5}.x=\frac{2}{15}\)

=> \(\frac{8}{5}.x=\frac{2}{15}\)

=> \(x=\frac{2}{15}:\frac{8}{5}\)

=> \(x=\frac{1}{12}\)

Vậy \(x=\frac{1}{12}\).

Chúc bạn học tốt!

Answer 2

\(\frac{7}{5}+\frac{1}{5}x=\)\(\frac{2}{15}\)

\(\frac{1}{5}x\)\(=\frac{2}{15}-\frac{7}{5}\)

\(\frac{1}{5}x=\frac{-19}{15}\)

\(x=\frac{-19}{15}:\frac{1}{5}\)

\(x=\frac{-19}{3}\)

Vậy x = \(\frac{-19}{3}\)

Học tốt nha!!!:)))
