Answer:
x=10
y=40
Explanation:
The shape is a parallelogram, therefore we know that opposite sides are equal to each other. So,
x + 18 = 3x - 2
Add 2 to both sides and subtract x from both sides
20 = 2x
divide both sides by 2
10 = x
Now, we have the other two sides;
4x = y
We already know that x = 10, so just plug that into the equation.
4(10) = y
40 = y
