Answer:
The age of Noelle = 20 years
Age of Noelle's dad = 54 years
Step-by-step explanation:
Here, Let us assume:
The age of Noelle's age = m years
So, the age of Noelle's dad = 3 x ( Age of Noelle) - 6 = 3(m) - 6
Also, sum of both the ages = 74
So, sum of (Noelle's age + Noelle's dad's) age = 74 years
⇒ m + ( 3 m - 6) = 74
or, 4 m = 74+ 6 = 80
or,m = 80 / 4 = 20
⇒ m = 20
Hence, the age of Noelle = m - 3 = 20 years
Age of Noelle's dad = 3 m - 6 = 3(20) - 6 = 54 years
