一些语句的10的补 [英] 10's complement of a number statement

问题描述

  

的值，X，Y，如果47x80是yaya0的10的补：

我计算yaya0的10的补数是10万yaya0然后。

  47x80 = 100,000 yaya0
 

现在如何找到价值？

解决方案

  47080 + 100X = 100000  - （10000y + 1000A + 100Y + 10A）
52920 = 100X + 10100y + 1010A
 

==> A = 2 否则你那​​倒得到2几十

  50900 = 100X + 10100y
 

这可以被分割 5 = Y 和 9 = X + Y

所以

  A = 2
X = 4
Y = 5
 

The values of a,x,y if 47x80 is the 10's complement of yaya0 is:

I calculated the 10's complement of yaya0 to be 100,000-yaya0 and then.

   47x80=100,000-yaya0

Now how to find values ?

解决方案

47080 + 100x = 100000 - (10000y + 1000a + 100y + 10a)
52920 = 100x + 10100y + 1010a

==> a = 2 otherwise you won`t get the 2 as tens

50900 = 100x + 10100y

this can be split up in 5 = y and 9 = x + y

so

a = 2
x = 4
y = 5
