    Answer:

      [x, y, z] = [7, 17, -15]

    Step-by-step 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
