Q53 - Algebraic equations

For which values of a is the equation 3x + a = 3 determined? A) For a ≠ −3 B) For a ≠ 3 C) For no value of a D) For a ≠ 0 E) For any value of a
Pinned

The correct answer is E) For any value of a.

"Determined" means exactly one solution. 3x = 3 − a gives x = (3 − a)/3, and since the coefficient of x is 3 and never zero, there's always exactly one solution, whatever a is.

a is only a constant term, so no value of it can break the equation.
