List the multiples of 42
42: 1 2 3 6 7 14 21 42
Then see which of the multiples add up to 13
1 x 42 = 42 --> 1 + 42
13
2 x 21 = 42 --> 2 + 21
13
3 x 14 = 42 --> 3 + 14
13
6 x 7 = 42 --> 6 + 7 = 13

Answer:
The answer is (2,3)
Step-by-step explanation:
Consider inequality
This inequality is equivalent to inequality 
This means that 
The greatest integer number n, such that
when dividing by 7 gives the remainder 4 is 39. Then subtract 7, you get 32, then 25 and so on.
When n=-39, -32, -25, -18, -11, -4, 4, 11, 18, 25, 32, 39 then dividing by 7 the remainder is 4.
Answer: 12 integers.
