$- \frac{7}{3}$
to get

$\frac{3}{7}$

Answer 1

◀HERE'S YOUR ANSWER▶

Let, the number be x.

Then,
$2( - \frac{7}{3} ) + x = \frac{3}{7} \\ or \: \: - \frac{14}{3} + x = \frac{3}{7} \\ or \: \: x = \frac{3}{7} + \frac{14}{3} \\ or \: \: x = \frac{107}{21}$

HOPE THIS ⬆ HELPS YOU

Answer 2

let the number be x
Then
x + 2(-7/3) = 3/7
x + 2 x -7/3 = 3/7
x + (-14/3) = 3/7
x - 14/3 = 3/7
x = 3/7 + 14/3
x = 9/21 + 98/21   (LCM = 21)
x = 107/21
