Answer:
x=199 and y=158
Step-by-step
Let x and y be two numbers
Given that the sum of the two numbers is 357, it may be written as
difference of the two numbers is 41, it may be written as
Now adding (1) and (2), we get
_______________________________________
_______________________________________
(Where y is in alternative signs so it may be cancelled)
Therefore
now substituting x=199 in (1) we get
Therefore
Answer:

Answer:
I'm not sure I understand but if you want more math to do look up Quizlet and do some of those tests
