I need to make e the subject of the formula T = n(1+e) / (1-e) Forgot how to do these complicated ones

Expand the brackets on both sides. 3. Collect all terms containing e at the LHS of the equation, all others at the RHS: 4. Factor out e at the LHS. 5. Divide both sides of the equation by -( T + n)
On point 4 you get e (- n - T) = n - T don't you?
Oh so e = - 1 is this correct?

Thanks
