Question

Solve w/3-3/w=0

Answer 1

There are a couple of ways you can solve this equation both of which will give you the same answer.

First Way:

w/3-3/w=0
w/3=3/w Cross multiplying gives:
(w)(w)=(3)(3)
w^2=9
w=+/-3

Second Way:

w/3-3/w=0
w/3=3/w Multiplying both sides by w gives:
(w)(w)/3=(3/w)(w)
w^2/3=3 Multiplying both sides by 3 gives:
(3)(w^2)/3=(3)(3)
w^2=9
w=+/-3
