Answer 2

Answer:

Let the rational number be x so it should be in the form of p/q where q is not equal to 0.

Explanation:

According to the question,

2x-7/3=3/7

$2x - \frac{7}{3} = \frac{3}{7}$

$2x = \frac{3}{7} + \frac{7}{3} \\ x = \frac{9 + 49}{21}$

$2x = \frac{58}{21}$

$x = \frac{58}{21×2}$

$x = \frac{58}{42}$

$x = \frac{29}{21}$
