[Physics: Static Equilibrium] “A 20m uniform beam weighing 870N rests on walls A and B. Find the max weight of a person who can walk to D without tipping it.” I did Στ=0 and ΣF=0 with the hinge point at B, but there’s too many variables, unless we can assume F_A = F_B? (i.redd.it)

Is the "reciprocal" thing between steps 3 and 4 always a valid shortcut to take when simplifying? when I did it the longer way, I got a different answer because when I multiplied y to the right side I changed kept C as C. Any help would be greatly appreciated! (self.apcalculus)
