Question

Solve ln y = kt for y

Answer 1

Y is already solved because y=kt

Answer 2

Do you mean solve
(In)(y)=(k)(t) for y?

If so then all you do is divided (In) on both sides and you'll get

Y=(k)(t)/(In)

The basic thing you need to know when solving for a variable is that you want to make it isolated.

On the other-hand, if you meant how do you solve for y=(k)(t) for y, then it's already solved.
