Answer:
[x, y, z] = [7, 17, -15]
Explanation:
The list equation resolves to four equations involving corresponding list elements:
5 -x = -2 ⇒ x = 7
-8 -7 = z ⇒ z = -15
2 -11 = 13 ⇒ looks like a wrong sign somewhere; this is FALSE
y -4 = 13 ⇒ y = 17

Comment on the question
Since one of the equations turns out to be false, it makes us suspect there may be typos in the others as well. YMMV
