1336 B.C.
However, seeing as how thats clearly out of the range of the answer you were looking for, I'll do the number crunching.
The value A will represent King Tut's age at his death.
The value B will represent King Eros' age at his death.
The value C will represent King Eros' year of death.
The Value D will represent King Tut's year of birth.
King Tut was murdered at age 9.
A=9
Now that we have the value of A, we can determine B from subtracting A from our constant of their combined ages, 100.
B=100-A (B=91)
We have King Eros' age at death. Our constant, 40BC (-40AD, for easier math) will have B added to it, to determine King Tut's year of birth.
C=(-40)+B (C=51)
Now, all thats left to do is add the constant 120 to C, to bring us to the year of King Tut's birth.
D=51+120 (D=171)
King Tut was born in the year 171.
EDIT -
He died at age 9, not 14. Fixed.
