Answer:

#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#
