Use the property of parallelograms to solve for the missing variable

x = 30, y = 6

Step-by-step explanation:

Here, we want to use the property of parallelograms

mathematically, the lengths of the parallel sides are equal

This mean:

2y + 3 = y + 9

2y - y = 9-3

y = 6

To get x;

Angles that face each other are supplementary; meaning they add up to 180

Thus, we have that

4x + 2x = 180

6x = 180

x = 180/6

x = 30
