What happens when two people exert pressure on an object from opposite sides in opposite directions?

When pressure is exerted on an object from opposite sides in opposite directions, the two forces either get cancelled if they are equal in magnitude or the force that is more in magnitude comes in play.
The object gets pulled to that side where the magnitude of force is greater.
