The age of a father is 2 less than 7 times the age of his son. in 3 years, the sum of their ages will be 52. if the son age is s years, which equation models this situation? a. (s+3)+[(7s-2)+3}=52 b. 3s+3+3(7s-2)= 52 c. s+(7s-2)=52 d. (s-3)+(7s-2)-3=52

First,
the age of the son: s
the age of the father is 2 less than 7 times the age of his son: 7s - 2
In 3 years, the sum of their ages will be 52,
In 3 years, the age of the sun will increase 3, so s+3. Also, the age of his father also increase 3, (7s - 2) + 3

(s+3) + [(7s-2) + 3] = 52 is the equation. 

Igot 108 hope that’s right !
