Answer: (6, 9), (3, 13)
Step-by-step explanation:
Left picture:
opposite side of parallelograms are congruent (equal)
3x = 18 3y - 1 = 26
÷3 ÷3 +1 +1
x = 6 3y = 27
÷3 ÷3
y = 9
**************************************************************************
Right picture:
diagonals of a parallelogram bisect each other so the left side and right sides of each diagonal are congruent
20 = y + 7
-7 -7
13 = y
16 = x + y
16 = x + 13
-13 -13
3 = x
