What should be added to -5/7 to get -2/3?

$\pmb{\mathbb{\text{\red{Solution:}}}}$

Let the number be 'x'.

$\bf{\purple{\frac{-5}{7} + x = \frac{ - 2}{3}}}$

$\implies{\bf{\orange{x = \frac{-2}{3}- \frac{-5}{7}}}}$

$\implies{\bf{\orange{x = \frac{-2}{3}- \frac{-5}{7}}}}$

$\implies{\bf{\orange{x = \frac{-2}{3} + \frac{5}{7}}}}$

$\implies{\bf{\orange{x = \frac{ - 14 + 15}{21}}}}$

$\implies{\bf{\green{x = \frac{1}{21}}}}$
