3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 18 + 3 = 0
-7x +21 = 0
-7x = -21
-7x/-7 = -21/-7
x = 3
y = -2(3) + 6
y = -6 + 6
y = 0
x= 3 y = 0

We have that AB || DC.

By a similar argument used to prove that AEB ≅ CED,we can show that (AED) ≅ CEB by (SAS) . So, ∠CAD ≅ ∠ (ACB) by CPCTC. Therefore, AD || BC by the converse of the (
ALTERNATE INTERIOR ANGLES) theorem. Since both pair of opposite sides are parallel, quadrilateral ABCD is a parallelogram
