如果y直接变化为x,如果x = -6,当y = 2时,当y = -9,-8,-6,-5,-4,-3时,如何找到x?

回答:

#y = -9 rarr x = -17#

#y = -8 rarr x = -16#

#y = -6 rarr x = -14#

#y = -5 rarr x = -13#

#y = -4 rarr x = -12#

#y = -3 rarr x = -11#

说明:

如果 #Y# 直接变化为 #X#,那时候 #X# 增加或减少一个数字 #N#,所以会 #Y#.

如果 #Y = 2# 什么时候 #X = -6# 然后:

#y = -9 = 2-11 rarr x = -6-11 = -17#

#y = -8 = 2-10 rarr x = -6-10 = -16#

#y = -6 = 2-8 rarr x = -6-8 = -14#

#y = -5 = 2-7 rarr x = -6-7 = -13#

#y = -4 = 2-6 rarr x = -6-6 = -12#

#y = -3 = 2-5 rarr x = -6-5 = -11#
