發問:

Lee Ming will be three times as old as he is now in thirty fours year's time. How old he is now?

最佳解答:

Let Lee Ming be x years old now. After 34 years' time, he will be (x+34) years old, which is also 3x years old. Then x+34=3x 34=2x x=17 Therefore, Lee Ming is 17 years old now. Verification(驗算): Lee Ming is 17 years old, he will be 51 years old after 34 years. 51=3 X 17 The answer is correct.

其他解答:

x = lee ming's age now x + 34 yrs = 3x 34 = 2x x = 17 So lee ming is 17 now.
