Answer:

c) x = 6, y = 9

Step-by-step explanation:

The figure is a parallelogram. The diagonals of a parallelogram bisect each other, so each part of a given diagonal is equal to the other part.

3x = 2y

2x = y+3

Solving the second equation for y, we have ...

y = 2x -3

Substituting into the first equation gives ...

3x = 2(2x -3)

3x = 4x -6 . . . . simplify

6 = x . . . . . . . . .add 6 -3x

y = 2(6) -3 = 9 . . . . use the above expression for y

The values of x and y are (x, y) = (6, 9).
