Hi Forum!

I have found this question:

Find the horizontal line y=k that divides the area bounded by the curvesandin two equal parts.

What I thought:

Get the bounded area.

...

Divide it by two

and calculate that with line k equaling 18

But, if we calculate

This is because we are going to subtract the same area more than once, right?

The answer is probably something around 3 and 6 then.

I am not sure how to continue.

Thanks!
