You can put this solution on YOUR website!
Let +j+ = Justin's age
Let +m+ = Megan's age
---------------------
(1) +j+=+12+
(2) +j+=+%28+1%2F2+%29%2Am+-+10+
------------------------
(2) +12+=+%281%2F2%29%2Am+-+10+
(2) +22+=+%281%2F2%29%2Am+
Multiply both sides by +2+
(2) +m+=+44++
Megan is 44
--------------
check:
(2) +j+=+%28+1%2F2+%29%2Am+-+10+
(2) +12+=+%28+1%2F2+%29%2A44+-+10+
(2) +12+=+22+-+10+
(2) +12+=+12+
OK
