Question

The age of a father is 2 less than seven times the age of his son in three years the sum of their ages will be 52 if the sun's present age is s years which equation models this situation

Answer 1

Since the father’s age is represented by 7(s+3)-2, s=son’s age, and s+father’s age=52, fathers age=52-s.
Therefore 7(s+3)-2= 52-s.
