Answer:

Hii mate ❤✌

Step-by-step explanation:

the sum of the present ages of a father and son is 53 years.

f + s = 53

f = (53-s); use this from for substitution

:

four years ago, the father's age was four times the age of the son.

f - 4 = 4(s-4)

f - 4 = 4s - 16

f = 4s - 16 + 4

f = 4s - 12

replace f with (53-s)

53 - s = 4s - 12

53 + 12 = 4s + s

65 = 5s

s = 65/5

s = 13 is the son's age
