Good luck finding the correct answer, using the rubbish the other person posted.
Let Mi Ho's age, be M
Then Ah Zu's is: M + 6
We then get: M+-+4+=+%281%2F2%29%28M+%2B+6+-+4%29+%2B+7
M+-+4+=+%28M+%2B+2%29%2F2+%2B+7
M+-+%28M+%2B+2%29%2F2+=+7+%2B+4
2M - (M + 2) = 22 ------- Multiplying by LCD, 2
2M - M - 2 = 22
2M - M = 22 + 2
M, or Hi Ho is: highlight_green%28matrix%281%2C2%2C+24%2C+years-old%29%29
Ah Zu is:
