Answer :
The required value of x in the equation x - 7 = 11 is x = 18. Option D is correct.
To find the value of x in the equation x - 7 = 11, we can solve for x by isolating it on one side of the equation.
Adding 7 to both sides of the equation, we get:
x - 7 + 7 = 11 + 7
x = 18
Therefore, the value of x in the equation x - 7 = 11 is x = 18. Option D is correct.
