Final answer:
To solve the equation x + 2 = 11, subtract 2 from both sides of the equation to isolate the variable x. The value of x is 9.
Step-by-step explanation:
To solve the equation x + 2 = 11, we need to isolate the variable x on one side of the equation. We can do this by subtracting 2 from both sides of the equation:
x + 2 - 2 = 11 - 2
x = 9
Therefore, the value of x is 9, so the correct answer is A) x = 9.
