First I'll tell you the answer. 2. Then I'll show you how to check it. 3. Then I'll tell you how to find it. 1. The answer is "I am 44 now" 2. I am 44 years old. In 20 years I'll be 64. 12 years ago I was 32. And 64 = 2 times 32. 3. I am x years old. In 20 years I'll be x+20. 12 years ago I was x-12. And x+20 = 2 times x-12. So: x + 20 = 2(x - 12) Solve that and you'll get 44. Do you see that from 2 and 3 that often setting up a word problem is exactly the same process as checking it when you know the answer? Just "check" it using x. Then solve. Edwin```
