Question

6. Solve for x : 16/x-1=15/x+1 ; x=0,-1

Answer 1

Answer:

The solution is ±4

Step-by-step explanation:

Answer 2

Given :

16/x - 1 = 15 /( x+1 ) where x not = 0 or -1 .

Solving the equation,

I 6 - x / x = 15/(x +1)

Cross - multiplying the equation,

(16 - x)(x+1) = 15x

=> 16x +16 - x^2 - x = 15x .

=> x^2 = 16x -15x - x +16

=> x^2= 16 .

Taking square roots on both sides,

x = ± 4
