O-Level Moments Question

Many schools have done moments recently. Here’s a problem that shows up a lot….

Question: A meter stick is pivoted for balance with a 50 N force (down) at one end and a 30 N force down at the other end. Where is the pivot point for balance? (Hint: The key to this problem is to take the one distance as x and the other distance as 1 – x. Now set up the balance equation.)
