N/2+5=3
move +5 to the other side
sign changes from +5 to -5
N/2+5-5= 3-5
N/2= -2
Mutiply both sides by 2/1
N/2*2/1 - Cross out 2 and 2 , divide by 2 then becomes N
-2(2)/1= -4/1= -4
N= -4
Answer : N= -4
The 3rd equation, as if you solve for x as shown, you will end up with equation x=8.

Step-by-step explanation:
Read the article and review the phases of mitosis.
Mitosis
we have
![V(x)=x^3-12x^2+48x-64](https://tex.z-dn.net/?f=V%28x%29%3Dx%5E3-12x%5E2%2B48x-64)
we know that
The volume of a cube is equal to
![V=b^{3}](https://tex.z-dn.net/?f=V%3Db%5E%7B3%7D)
where
b is the length side of a cube
Using a graph tool------> find the roots of the polynomial
see the attached figure
x=4
so
![x^3-12x^2+48x-64=(x-4)^{3}](https://tex.z-dn.net/?f=x%5E3-12x%5E2%2B48x-64%3D%28x-4%29%5E%7B3%7D)
therefore
<u>The answer is</u>
the length side of a cube is equal to (x-4)
