Question

(5x-1).(2x-\(\frac{1}{3}\))=0

Answer 1

(5x-1) .(2x-1/3) =0

* 5x-1=0 * 2x-1/3=0

5x= o+1 2x=0+1/3

5x=1 2x=1/3

x=1/5 x=1/6

x=1/5; 1/6

Answer 2

(5x - 1).(2x - \(\frac{1}{3}\)) = 0

\(\left\{{}\begin{matrix}5x-1=0\\2x-\frac{1}{3}=0\end{matrix}\right.\) => \(\left\{{}\begin{matrix}5x=0+1\\2x=0+\frac{1}{3}\end{matrix}\right.\) => \(\left\{{}\begin{matrix}5x=1\\2x=\frac{1}{3}\end{matrix}\right.\)

=> \(\left\{{}\begin{matrix}x=\frac{1}{5}\\x=\frac{1}{6}\end{matrix}\right.\)

Vậy x ∈ \(\left\{\frac{1}{5};\frac{1}{6}\right\}\)
