Which inequality is true for every real value of x?

Answer and explanation

Correct answer: 2x + 3 < 2x + 5

The governing concept is solving an inequality by simplifying both sides and identifying whether the variable remains. For option A, subtracting 2x from both sides gives 3 < 5. This statement is true independently of x, so every real number satisfies the original inequality. In option B, cancellation gives 5 < 3, which is false for every x. In option C, subtracting x gives 1 < -1, also always false. In option D, subtracting 3x gives 0 > 1, which is false. Therefore only option A represents an inequality with the solution set all real numbers. The result is an identity-type inequality rather than a condition restricting x.
