To solve the question,we can set two eqautions:
Let Micheal’s age be x.
Let Brandon’s age be y.
As Micheal is 4 times as old:
x/4 = y
x = 4y... (1)
As Micheal is 27 years older:
x - y = 27...(2)
Put (1) into (2), where x = 4y:
(4y) - y = 27
3y = 27
y = 9
Therefore, Brandon is 9 years old.
We can then find Micheal’s age:
9×4
=36
Therefore Micheal is 36 years old.
Hope it helps!
