<em><u>Answer:</u></em>
x. a.
y. b
z. c.
<em><u>Step-by-step explanation:</u></em>
So from the middle column, we know that each row or colum must be -12 because 1 - 8 - 5. x + 1 - 12 should be = - 12, so x -11 = 12, so x = -1
For z, - 12 + 3 + z = -12, so z = -3
For y, y - 5 + z = -12, but we know z so we can plug in -3:
y - 5 - 3 = - 12
y - 8 = -12
so y must be -4
