Question 1176127
.


As an attentive reader,  I'd like to report you about discrepancies in your post.



The number of hamburgers and the number of bottled water is just given in the problem.


So, there is no need to introduce the unknowns x and y  for these quantities - we just know them from the condition.




And as a conclusion,  may  I  ask you:



<H3>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Do you read, in general, what you post ?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;And if you read, then do you understand what you read ?</H3>

But it looks like you &nbsp;IGNORED &nbsp;that my previous post.



<H1>&nbsp;&nbsp;&nbsp;&nbsp;Hello,  If you will ignore my posts,</H1><H1>&nbsp;&nbsp;&nbsp;&nbsp;then in response, I will DELETE yours.</H1>
