Answer:
x = 2
y = 9
Step-by-step explanation:
Opposite sides of a parallelogram are the same length. This relation is used to make equations with the given side lengths.
<u>Top and Bottom</u>
4x +20 = x +26
3x = 6 . . . . . . . . . . . subtract x+20 from both sides
x = 2 . . . . . . . . . divide by 3
<u>Left and Right</u>
7y = 6y + 9
y = 9 . . . . . . . . . subtract 6y from both sides
