Let x = the year of birth of the youngest, then x+1 will be the year of birth of the next oldest and x+2 will be the year of birth of the eldest friend.
So we need to find x.
x+(x+1)+(x+2) = 5961
3x+3 = 5961 Subtract 3 from both sides.
3x = 5958 Divide both sides by 3.
x = 1986
x+1 = 1987
x+2 = 1988
Check:
1986+1987+1988 = 5961
