The area under the graph y= 4 + 2x from x=0 to x=4 is divided into two equal parts by the line x=k. Find the value of k.
Please ive been stuck on this for years

I assume that 0 < k < 4.
From the title of your post I assume that you want to calculate the area by integration (which isn't necessary with your problem). You calculate 2 areas which should be equal:
It is now
You'll get a quadratic equation:
The negative solution doesn't fit into your problem. So k = 2.47...
