If a equals 4, what is the value of x?

Explanation:
To find x from a given a, you need the equation that links x and a. Substituting the known value of a into that equation and solving for x gives the result. If the relationship is x = a − 11, then with a = 4 you get x = 4 − 11 = −7. That value fits the equation, so it’s the correct choice for that relation. The other numbers don’t satisfy the equation when a equals 4. Note that, as written, the problem doesn’t show the linking equation, so x can’t be determined uniquely without it.
