The literal translation of the condition to the Math equations is THIS:
M = S + 22 (1)
(M+8) + (S+8) = 102 (2)
Substitute (1) into equation (2), replacing M. You will get
((S+22)+8) + (S+8) = 102,
2S + 22 + 8 + 8 = 102
2S = 102 - (22 + 8 + 8)
2S = 64 ====> S = = 32.
Answer. The son is 32 years old. The man (the father) is 22 years older : 32 + 22 = 54.
Solved.
