Since the ground floor has 52 windows, and every floor, here are 6 fewer windows than the floor below it, we make a expression.
52-y=x.
We are trying to solve for x, not y.
In order to get 'y,' you have to multiply 8 by 6. Which is going to be 48.
(If you don't know multiplication, respectively.)
So now that we solved for y, =48 .... 52-48= ....... = x
Now all we have to do is simply subtract.
x=4.
So the answer to the problem is 4 windows on the 8th floor.
