Question

if 1/y proportional with 1/x-y then prove that x is proportional to y​

Answer 1

Answer:

see below

Step-by-step explanation:

1/y proportional with 1/x-y

1/y ∞ 1/(x-y)

1/y = k 1/(x-y)

(1/y) / (1/(x-y)) = k

(x-y) / y = k

x/y - y/y = k

x/y - 1 = k

x/y = k + 1

x/y = k'

x = k' y

x ∞ y

x is proportional to y

hence proved
