X=13 is the best correct answer!
First step: Collecting like terms of variables. We’ll subtract 5x-4x which would be just x.
Second: 23-10 which would be 13.
Hope it was helpful!

To solve the equation 5x+10 = 4x + 23, we must isolate the variable x on one side of the equation and move all constant terms to the other side of the equation. (Here I am going to move the x terms to the left side and the constant terms to the right side).

5x - 4x +10 -10 = 4x-4x + 23 -10
After combining like terms, we actually get our answer:
x= 13

Therefore, the answer is A.

Keep in mind that you are trying to cancel out items on one side of the equation, which in turn “moves” these terms to the other side.

Hope this helps!
