Start naming things, and use the relationships between the people and the times to set up this "age" word problem:Ten years ago a man was as old as his wife is now. The man is now twice as old as his wife was then. How old are they both now?
You can check the answer to any "solving" exercise by plugging your solution back into the original problem, and seeing if it works. In your case:so its (h-10)=(w) and (h)=2(w-10)?
i get w=30 h=40 is that rite?
