Would anyone be able to assist me in solving this puzzle? It should be simple, though I have no background in physics or math.

So here's the situation. Imagine you have a 5 meter long cantilever beam, with a 100kg man standing at 4.6498985 meters from the wall. A crane hook is attached to the end of the beam imparting an upward force on the beam of 936.92865 Newtons (N) (a Newton is a unit of force attained by multiplying a mass such as 1 kilogram by an acceleration such as the gravitational constant 9.81 meters per second per second here on Earth, i.e. 1kg X 9.81 m/s^{2}= 9.81N). Solving for the reaction forces at the wall, keeping 6 or 7 decimal places in your calculation to avoid round off error.

I asked about this on a different forum, and just got a few very vague hints, one of which was definitely not right. I should explain briefly that while I appreciate hints/explanations, this is not for a school project or anything (I've been out of school for nearly two decades). I'm just looking for the answer to the problem, which is part of a puzzle I'm solving (for fun). So basically, all I need is a number.

Thank you in advance for any help you might have, I appreciate it.
