Question

Me. Brown 18 years older than his son. Their total age is 60 years. Calculate Mr. Brown's age and his son's age ?​

Answer 1

Answer:

The age of Mr. brown and his son are 39 and 21 years respectively

Step-by-step explanation:

let, Mr. Brown's age = y years

and his son's age= x years

by the 1st condition

y = x + 18

-x + y = 18 -------------(1)

by the second condition

x + y = 60 --------------(2)

adding equation (1) and (2)

    -x + y = 18

+    x + y = 60

-----------------------

        2y = 78

        y = 78 / 2

      y = 39

substituting y = 39 in equation (1)

-x + y = 18

-x + 39 = 18

-x = 18 - 39

-x = - 21

x = 21

the age of Mr. brown and his son are 39 and 21 years respectively
