please mark my answer as brainliest

Answer 2

Explanation:

$\frac{x - a}{x + b} = \frac{a + b}{a - b}$

$= > (x - a)(a - b) = (a + b)(x + b)$

$= > ax - bx - {a}^{2} + ab = ax + ab + bx + {b}^{2}$

$= > ax - ax - bx - bx + ab - ab = {b}^{2} + {a}^{2}$

$= > - 2bx = {a}^{2} + {b}^{2}$

$= > x = - \frac{ {a}^{2} + {b}^{2} }{2b}$
