What is the solution of the inequality x/7 > 2?

Answer and explanation

Correct answer: x > 14

The governing concept is solving a fractional linear inequality by multiplying both sides by the denominator. In x/7 > 2, multiply both sides by 7 to obtain x > 14. Since 7 is positive, the inequality direction remains unchanged. Therefore option A is correct. A check with x = 15 gives 15/7, which is greater than 2, while x = 14 gives exactly 2 and is excluded because the original sign is strict. Option B reverses the direction without a negative multiplier. Options C and D incorrectly divide by 7 again or confuse multiplication with division. The denominator is a positive constant, so multiplying by it is valid and produces the unique solution x > 14.
