Answer 2

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

$10x - 1 \div x = 3$

$= > \frac{10x - 1}{x} = 3$

$= > 10x - 1 = 3x$

$= > 10x - 3x = 1$

$= > 7x = 1$

$\bold{= > x = \frac{1}{7} }$

Check:-

$= > \frac{10x - 1}{x} = 3$

$= > \frac{10 \times \frac{1}{7} - 1 }{ \frac{1}{7} }$

$= > \frac{ \frac{10}{7} - 1 }{ \frac{1}{7} }$

$= > \frac{10 - 7}{7} \times \frac{7}{1}$

$= > \frac{3}{7} \times \frac{7}{1} = 3$

Hence ,proved and checked .
