Answer: A. x = 11.
Explanation:
To solve for x in the equation x - 4 = 7, we need to isolate x on one side of the equation.
To do this, we can add 4 to both sides of the equation to cancel out the -4 on the left side:
x - 4 + 4 = 7 + 4
This simplifies to:
x = 11
Therefore, the solution to the equation x - 4 = 7 is x = 11.
So, the correct answer is A. x = 11.
