Question

A man is 42 years old and his sons is 12 years old in how many years will the age of the sun we half the age of the man and that time​

Answer 1

Let x = the unknown number of years

The man is now 42 and his son is 12. In x years, this is how old they'll be:

Man's Age = (42 + x) years old

Son's Age = (12 + x) years old

Now in x years, the son will be one-half as old as his dad. That's the key piece of information that allows us to equate their two ages:

Son's Age = (1/2)*Man's Age

12 + x = (1/2)*(42 + x)

12 + x = 21 + x/2

Now solve for x and let me know what you get (in the comments) and I'll tell you if you got it right.
