Plz step by step understanding on this answer !!!!!!!!

Answer:
Option A
Option C
Option D
Step-by-step explanation:
Option A
sum the number two to both sides of the equality
X-2=0
X-2+2=2
So we have X=2
Option B
multiply the whole equality by 3
(1/3)X=2
3*(1/3)X=2*3
we have X=6
this is not the solution requested
Option C
divide the whole equality by 4
8=4X
8/4=(4X)/4
we have X=2
Option D
lets obtain the square root of every side of the equality
X^2=4
[tex]\sqrt{x^{2}}[/tex] = [tex]\sqrt{4}[/tex]
X=2
Option E
6-X=3
6-3=x
x=3
this is not the solution requested
