Step-by-step explanation:
For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is
.

Doubling the lengths of the sides of a rectangle quadruple the area
<h3>How to determine the effect?</h3>
Let the dimension of the rectangle be L and W.
So, the area is
A = LW
When the lengths are doubled, we have:
A2 = 2L * 2W
This gives
A2 = 4LW
This means that the initial area is multiplied by 4
Hence, doubling the lengths of the sides of a rectangle quadruple the area
