Last year, I sent a series of questions and comments to WyzAnt.  Here is Question 1 and their response:
 
1.       Occasionally, a student will post multiple questions (perhaps, “wanting someone to do their homework for them”).  Can frequency of requests be limited?

Students are permitted to ask as many questions as they would like.  Our Content Review Team does monitor activity on the page and will remove a question if it seems to be a case of academic dishonesty.

Let x be one of the numbers, and let y be the one that is 5 more than 4 times the other, with both adding up to 35.
 
Then
 
x + y = 35
y = 5 + 4x
 
Just solve for x and y from the above 2 equations.  Take y = 5 + 4x from the bottom equation, plug it into the top equation and get
 
x + (5 + 4x) = 35
5x = 30
x = 6
 
Then from the bottom equation, y = 5 + 4(6) = 29
 
Test the answers:
 
x + y = 6 + 29 = 35 (good)
5 + 4x = 5 + 4(6) = 29 = y (good)
