Is a sum of two numbers equal to the product of the two numbers?相关知识点: 试题来源: 解析 存在这样的数,例如x = 2和y = 2,它们的和等于它们的乘积。 假设两个数为x和y,根据题意,有等式x + y = xy。通过代数变换,可以得到(x - 1)(y - 1) = 1。当x = 2时,y = 2,满足等式。因此...
Let x and y be the two numbers, where x is the lesser of the two numbers and y is the number desired. From the given information it follows that xy=160 and x=2y-4, from which it follows that (2y-4)y=160. Dividing both sides of the last equation by 2 gives (y-2)y=80. ...
