Which ordered pair is a solution of the equation? 3x−y=13
A only (6,5)
B Only (3,-4)
C Both (6,5) (3,-4)
D Neither

Your answer is (3, -4) .. to get that I plugged each set into the equation and solved to figure out which ordered pair makes this statement equivalent.. I got 13=13 after plugging in and solving so that makes it equivalent the other ordered pair makes an inequivalent outcome which was 9=13 ... I hope this helps

D Neither

Step-by-step explanation:

3x-y=13

3x-y=13-13

3x-y=0

Answer x = 33°y = 38°z = 109°explanations first you have to understand all properties of a parallelgram for you to answer this questions 1). opposite sides are parallel and equal, 2). interior opposite angles are equal. 3). if a diagonal drawn, is acts as a transvers to the opposite sides. solving for x the diagonal drown makes the angle 33 to be alternate to x. alternate angles are equal. so, x = 33o solving for y the angle 33, 109 and y makes the angles in a triangle from the diagram. angles in a triangle add up to 180. 33+109+y=180 y=180-(33+109) y=38° solving for z opposite interior angles in a parallelogram are equal. the angle 109 and z are opposite interior angles. so z = 109o
