Re: Q&A - P3 Math

Still stuck on algebra....
Let x years old be the age of his son.

The man's age will be 4x years old.

Four years ago, the son's age is (x-4) years old.

Hence the man's age is 6*(x-4) = (6x-24) years old.

Form an equation with the man's current age and his age 4 years ago.

You should get:

6x-24+4 = 4x

2x-20 = 0

x = 10

The son's age is 10 years old and the man's age is 40 years old.

I don't remember primary three math to be so complicated.

Thanks, but I need help with modeling for this question. I'm still stuck in algebra days, so can't help my kid with models....
