a=2*b1
a1=b
a-a1 = b-b1
Solve the equations, b=18

标题: My translation may be not so good. 这里是原题。

Excuse my poor English. Here is the original question in English ...
 
John and Jane are a couple. John is now 24 years old. He is now twice as old as Jane was, when he was as old as Jane is now.www.ddhw.com
 
I changed the question a little bit to simplify it in Chinese.

标题: 原题可能有问题

 
如果“when he was as old as Jane is now”是问句,则提问:在那一年他与珍现在的年龄相同?www.ddhw.com
 
如果“when he was as old as Jane is now”是时间条件句,则此题缺少提问
