Answer:

w = - 3 only

Explanation:

Given


(7)/(w+4) =
(5)/(w+4) -
(6)/(w)

Note that w ≠ - 4, 0 as this would give division by 0

Multiply through by w(w + 4)

7w = 5w - 6(w + 4) ← distribute and simplify right side

7w = 5w - 6w - 24

7w = - w - 24 ( add w to both sides )

8w = - 24 ( divide both sides by 8 )

w = - 3
