To find the value of y in parallelogram upper L upper M upper N upper O, we can set up an equation using the fact that the diagonals of a parallelogram bisect each other.

From the given information, we know that part of diagonal upper L upper N is labeled y, and the other part is labeled 3x. This means that the diagonal upper L upper N can be expressed as y + 3x.

Similarly, part of diagonal upper M upper O is labeled y + 12, and the other part is labeled 6x. This means that the diagonal upper M upper O can be expressed as y + 12 + 6x.

Since the diagonals bisect each other, we can set up the equation:

y + 3x = y + 12 + 6x

By simplifying and rearranging the equation, we get:

3x - 6x = 12 - y

-3x = 12 - y

To find the value of y, we need to have a numerical value for x. Without that information, we cannot determine the value of y. Therefore, the answer cannot be determined with the given information.
