Plz step by step understanding on this 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

=

X=2

Option E

6-X=3

6-3=x

x=3

this is not the solution requested
