For a parallelogram opposite sides are equal, so set
AB = CD and BC = AD.

1) 20y = 4y + 32 → 16y = 32 → y = 2.
2) 1 + 3x = 6x − 20 → 1 − 20 = 6x − 3x → −19 = 3x −? (better step) 1 + 3x = 6x − 20 → 1 + 20 = 6x − 3x → 21 = 3x → x = 7.

(Alternatively: 1 + 3x = 6x − 20 → 1 − 3x = −20 → −3x = −21 → x = 7.)

Check lengths: AB = 40, BC = 22, CD = 40, AD = 22, so the pairs match.

Thus x = 7 and y = 2.
