Find values of x and y for which abcd must be a parallelogram. the diagram is not to
scale.

a. x = 8, y = 17
b. x = 6, y = 8
c. x = 8, y = 10
d. x = 8, y = 6

3x - 14 = x + 2
- x         - x
2x - 14 = 2
    + 14 + 14
       2x = 16
        2      2
         x = 8

4y - 7 = y + 11
- y       - y
3y - 7 = 11
    + 7  + 7
      3x = 18
       3      3
       x = 6
 (x, y) = (8, 6)

The answer is D.

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
