Answer:

1/(a + b + x) = 1/a + 1/b + 1/x

=> 1/(a + b + x) - 1/x = 1/a + 1/b

Take LCM on both the sides

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

=> -(a + b)/ax + bx + x^2 = (a + b)/ab

(a + b) is common on both sides of the equation. Cancel them. (-) sign is taken common from the LHS.

=> -ab = ax + bx + x^2

=> x^2 + ax + bx + ab = 0

=> x(x + a) + b(x + a) = 0

=> (x + b)(x + a) = 0

=> x = -b, -a
