Answer:

x=3 and y=4

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, or equal.

Therefore, (4x+6) = (7x-3) and (4y-3) = (3y+1)

4x+6 = 7x-3 –– Subtract 4x from both sides

6=3x-3 –– Add 3 to both sides

9=3x –– Divide both sides by 3 to get x alone

3=x

4y-3 = 3y+1 –– Subtract 3y from both sides

y-3=1 –– Add 3 to both sides

y=4

Check by substituting:

4(3)+6 = 7(3)-3

12+6 = 21-3

18 = 18

4(4)-3 = 3(4)+1

16-3 = 12+1

13 = 13
