Answer:
x = 4 and y = 9
Step-by-step explanation:
This is a parallelogram, which we can tell because of the arrows. Basically, opposite sides are parallel. By definition, then, opposite sides of this polygon are equal: LM = ON and LO = MN. That means we can set the various expressions equal to each other:
LM = ON ⇒ 6x - 7 = 2x + 9 ⇒ 4x = 16 ⇒ x = 4
LO = MN ⇒ 12 = y + 3 ⇒ y = 9
Thus, x = 4 and y = 9.
Hope this helps!
