Question

please solve this question step by step​

Answer 1

Answer:

1

Step-by-step explanation:

cross multiply by (x+b) (a+b) = (a-b) (x-b)

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

xa+xb - ba+bb = ax-ab - bx-bb

=-(a+b) /x+b)

Answer 2

Answer:

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

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

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

$bx + bx = - ab - ab$

$2bx = - 2ab$

$x = \frac{ - 2ab}{2b}$

$x = - a$
