Answer:
x = -24, y = 10
Explanation:
Since it's a parallelogram, you know that the opposite sides are equal in length. Thus, you can set the opposite sides equal to each other and isolate the variable.
To find x:
-x + 2 = 26
Subtract 2 from both sides
-x = 24
Divide each side by -1
x = -24
To find y:
6y - 8 = 52
Add 8 to both sides
6y = 60
Divide both sides by 6
y = 10
