Spain has a population of 2015. The men and women together number 1007, and the children together number 1537. How many children are there? How many women are there? How many men are there?

m+w+c = 2015
m+w = 1007, from this we would know that c = 1008

but then you say: the children together number 1537
What does that mean? together with what?

check your typing, the question is flawed
Edited!!!! Spain has a population of 2015. The men and women together number is 1007, and the women and children together number is 1537. How many children are there? How many women are there? How many men are there?
Going with your original total:

m+w+c = 2015
m+w = 1007, from this we would know that c = 1008

women and children together number is 1537, but c = 1008
so w = 529

back to start: m+w+c = 2015
m+529+1008 = 2015
m = 478
