Explanation

Let brother's present age = x years

Then man's present age = x + 5 years

After 4 years:

Brother's age = x + 4

Man's age = x + 5 + 4 = x + 9

Sum of ages after 4 years = 45

So, (x + 4) + (x + 9) = 45

2x + 13 = 45

2x = 45 - 13

2x = 32

x = 16

Brother's present age = 16 years

Man's present age = x + 5 = 16 + 5 = 21 years
