THis is the Answer ...
4x = 20-12
4x = 8
x = 8/4
x = 2
A.) Subtract 4x from both sides, then divide by 4.

12 + 4x = 20
In other words, you are ask how to find x in a step by step process.
Let us work it out in a detailed order.
Subtract 12 from both sides.
12 -12 + 4x = 20 - 12
4x = 8 (answer)
Then, devide the answer by 4.
4x = 8
x = 2
Verify
12 + 4 *2 = 20
20 = 20
Therefore, the statement should be like this:
Subtract 12 from both sides then devide the answer by
4.
So, none of the above choices has a correct procedure in solving for x.

12+4x=20
=> 4x=20 - 12
=> x= (20 - 12) / 4
=> x = 8 / 4
=> x = 2
Ans : B.) Subtract 12 from 20 then divide the answer by 4.

12 + 4x = 20
12 = 20 - 4x
3 = 5 - x
3 + x = 5
x = 2
A is you answer

To solve you want to isolate the variable or get x by itself.
The logical steps to follow to isolate x are given in B.
If you try the other options you will see that x is not isolated, and therefore the equation cannot be solved.
