x=2.25m

Explanation:

First of all convert the masses into weight by multiplying them with the gravitational force which is 10
5*10=50N
20*10=200N
now use the formula moment=F*d
Also apply the the principle of moments which is the anticlockwise moment=clockwise moment
so F*d=F*d
50*9=200*x
450=200x
x=2.25m
