Which of the following should be done to both sides of the equation X +11 equals -17 to solve the value of X is it subtract 17 subtract 11 add 17 add 11

To solve for the value of X, you need to perform the same operation on both sides of the equation to keep it balanced. In this case, you should subtract 11 from both sides, since the equation is in the form X + 11 = -17. Thus, the correct answer is subtract 11.
