What are three consecutive odd intergers whose sum equals 121-the first integer: x+?+? = 121-x

x+?+?= 121-x


My son got this as a homework assignment and the teacher gave no return input. Looking at it, the answer doesn't seem possible based on addition logic:

x+ (x+2) + (x+4) = 121-x

odd+odd= even + Odd= Odd odd-odd= Even


So you get Odd= Even can't work as an integer. Am I missing something?
