Answer:

B

Step-by-step explanation:

All parallelograms have diagonals which bisect each other. This means the diagonals intersect and create equal lengths.

5y = 3x + 6

8x - 2 = 4x

Solve for x using 8x - 2 = 4x. Then substitute x into the other equation.

8x - 2 = 4x

-2 = -4x

1/2 = x

Substitute x = 1/2.

5y = 3(1/2) + 6

5y = 3/2 + 6

5y = 3/2 + 12/2

5y = 15/2

y = 15/10

y = 3/2 or 1.5
