Answer:
x=8
y=13
Explanation:
This shape is a parallelogram, and in a parallelogram, the diagonals bisect eachother. So then, you can write to equations:
2x=y+3
x+5=y
This is equal to:
2x-y=3
x-y=-5
Then, you can subtract the two equations, making it:
2x-y=3
-x+y=5
Then the result will be:
x=8
Now that we know what x is, you can find y by plugging it in to either equation.
8-y=-5
-y=-13
y=13
