A bricklayer weighing 800N stands 1 meter from one end of a scaffold 3 meters long. The scaffold weighs 750N. A pile of bricks weighing 320N is 1.50 meters from the other end of the scaffold. What force must be exerted on each end of the scaffold to support it?

Since you didn't read the homework rules... show us your work and answer first, then we can help you. We don't do your homework so you won't have to.

Hint: draw a free body diagram, and use the fact that the sum of moments about any point = 0 and the sum of vertical forces = 0. Take a stab at it, show us your work, and we'll be glad to help you along if you get stuck.
