1. The problem statement, all variables and given/known data

How far from a lens of focal length 50 mm must the object be placed if it is to form a virtual image magnified in size by a factor of 3?

2. Relevant equations

3. The attempt at a solution

I thought I could us the equation...

M = s'-f/f to get s' and then use...

1/f = 1/s + 1/s' to get the object distance

but I am not coming up with the right answer??
