Beam and Support Force Question

[G.T]

Homework Statement

A 7.20m long rigid beam with a mass of 105.9kg is supported at each end. A 64.8kg student stands 1.33m from support 1. How much upward force does each support exert on the beam? (Enter your answer for support 1 first, followed by your answer for support 2.)

"Moment of inertia", whatever that means, is not how you solve this problem.

Try writing the equations of static equilibrium for this beam, and then using them to solve for the unknown reactions.
