I think the original solver got this one wrong.
Let m = my age now, and h = his age now. My age is now 4 times is, so:

Twenty years later, his will be half mine, so:

Substituting 4*h for m (from the first equation) gives:

Subtracting h + 10 from each side gives:

So his age is currently 10 and mine is 40.
