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’s present 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

(7s-2)+3+(s+3) = 52

Step-by-step explanation:

Since s is the son's age, "two less than seven times" the son's age would be represented by 7s-2. To represent this in 3 years, we would add 3: (7s-2)+3. In 3 years, the son's age, s, would be represented by s+3. We are told that the sum of these ages will be 52; this gives us (7s-2)+3+(s+3) = 52.

To simplify this, combine like terms. 7s+s = 8s; -2+3+3 = 4. This gives us 8s+4=52.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
