Answer:
Brandson is 9 years old and Micheal is 36 years old
Explanation:
Let the age of Brandson be x years
then the age of Micheal be y years
According to the given condition
y=4x----------1
y= x+27-------2
From 1: x= y/4 --------3
Putting 3 in 2
y = y/4 +27
y= y+ 108/4
4y= y +108
4y - y= 108
3y= 108
y = 108/3
y= 36-----------4
Putting 4 in 1
36= 4x
x= 36/4= 9---------5
