Based on the modelling of the ages of Sam and Harry, the current ages of the two males are Sam is 36 years old, and Harry is 6 years old.
The system of equations are:
x = 6y
x = 12 + 4y
Use the substitution method to solve for y which is Harry's age:
6y = 12 + 4y
2y = 12
y = 12 / 2
y = 6 years
This means that Sam's age is:
x = 6y
= 6 x 6
= 36 years
