Which equation could be used to solve for the measure of angle O?

Circle N is shown with a quadrilateral OPQR inscribed inside it. Angle O is labeled x degrees. Angle P is labeled y degrees. Angle Q is labeled z degrees. Angle R is labeled w degrees.

x + z = 180
x + y = 180
x − (y + z) = 360
x + y + z = 360
