Linear equations with three variables

I just want to make sure I am writing these equations correctly. This is the word problem: The sum of three integers is 65. The sum of the second and third is 25 more than the first. If the third is subtracted from the sum of the first two, the difference is 17. Find the three integers.
 
I have:
 
x+y+z=65
y+z=25+x
x+y-z=17

Eve, assuming that x = 1st , y = 2nd, and z = 3rd integer, then you have done an outstanding job of setting up this problem. It is absolutely correct. Way to go!
