x = jhon years
y = jhon's brother years
"Jhon is 3 years older than his brother" -> x = y + 3
"In 3 years time the sum of theris ages will be 29 years" -> (x+3) + (y+3) = 29
Then we obtain the following system of equations:
x - y = 3
x + y = 23
Whose solution is x = 13, y = 10
I hope that it serves you
