Question 1067116

Ah Zu is 6 years older than his friend Mi Ho. Four years ago Mi Ho's age was 7 more than half of Ah Zu's age. What are their present ages?
<pre>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 = (1/2)(M + 6 - 4) + 7}}}
{{{M - 4 = (M + 2)/2 + 7}}}
{{{M - (M + 2)/2 = 7 + 4}}}
2M - (M + 2) = 22 ------- Multiplying by LCD, 2
2M - M - 2 = 22
2M - M = 22 + 2
M, or Hi Ho is: {{{highlight_green(matrix(1,2, 24, years-old))}}}
Ah Zu is: {{{highlight_green(matrix(1,6, 24, "+", "6," , or, 30, years-old))}}}
