Answer 1

[Hoàng Nguyên Trương]

Ta có : \(5\frac{8}{17}\div X+\left(-\frac{1}{17}\right)\div X+3\frac{1}{17}\div17\frac{1}{3}=\frac{4}{17}\)

Nên:    \(\left(5\frac{8}{17}+\left(-\frac{1}{17}\right)\right)\div X+\frac{52}{17}\div\frac{52}{3}=\frac{4}{17}\)

           \(5\frac{7}{17}\div X+\frac{52}{17}\times\frac{3}{52}=\frac{4}{17}\)

           \(\frac{92}{17}\div X+\frac{3}{17}=\frac{4}{17}\)

           \(\frac{92}{17}\div X=\frac{4}{17}-\frac{3}{17}\)

           \(\frac{92}{17}\div X=\frac{1}{17}\)

           \(X=\frac{92}{17}\div\frac{1}{17}\)

            \(X=92\)

Vậy \(X=92\)

Answer 2

[Louis Pasteur]

\(5\frac{8}{17}:x+\left(-\frac{1}{17}\right):x=\frac{52}{51}\)

\(\left(5\frac{8}{17}+-\frac{1}{17}\right):x=\frac{52}{51}\)

\(\frac{92}{17}:x=\frac{52}{51}\)

\(X=\frac{92}{17}:\frac{52}{51}=\frac{69}{13}\)
