Question

2/3 -1/3 :x=-1/5

Answer 1

\(\frac23-\frac13:x=-\frac15\)

\(\frac13\cdot\frac{1}{x}=\frac23-\left(-\frac15\right)\)

\(\frac{1}{3x}=\frac{13}{15}\)

\(\Longrightarrow15=39x\)

\(\Longrightarrow x=\frac{15}{39}=\frac{5}{13}\)

vậy \(x=\frac{5}{13}\)

Answer 2

\(\frac23-\frac13:x=-\frac15\)

\(\frac13:x=\frac23+\frac15=\) \(\frac{13}{15}\)

\(x=\frac13:\frac{13}{15}=\frac{5}{13}\)

Vậy \(x=\frac{5}{13}\)
