You can put this solution on YOUR website! Let your age be x while your brother's age be y
 From the second sentence, you are 5 years older than him. So the equation is:
 x = y + 5. . . . . .(i)
 From the third sentence, the sum of your ages becomes
 x + y = 27. . . . . .(ii)
 Solving simultaneously, using substitution.
 x = 16, y = 11
 .: you are 16yrs old
