Question

if a = 1/a-5 then find a-1/a​

Answer 1

a = 1/a - 5

Subtract 1/a from the above equation,

=> a - 1/a = (1/a - 5) - 1/a

=> a - 1/a = (1/a - 1/a) - 5

=> a - 1/a = 0 - 5

=> a - 1/a = -5

Hence, a-1/a = -5

Answer 2

Answer:

-5

Step-by-step explanation:

if a=1/a-5

a-1/a=-5

(a^2-1)/a=-5

.............(1)

and to find a-1/a

i e

=(a^2-1)/a

from equation (1)

=-5
