If we rechange these two numbers: one number to two times as many as its original value, and the other to four times as many as its original value, the average of the five numbers will become 13. Which two numbers have been changed?I only know that the total sum of the original numbers is 45(5×9), the total sum of the 5 numbers after the first change is 40(5×8), and the total sum of the 5 numbers after the second change is 65(13×5). What can I do next? Please help me with the problem.Thank you!

这就要求琬婷一方面要用英语准确地把她想要问的问题清晰地表达出来，只有这样网上"数学博士"才能明白你要问的问题；另一方面琬婷还必须能够正确理解网上"数学博士"对她所提问题的英语答复，这两者是相互依赖的，否则就不能正确地帮助你理解和解决问题，这就要求琬婷必须用英语进行正确地表述和理解。
