What is the solution of the inequality (x/5 > −1)?

Answer and explanation

Correct answer: x > −5

The governing rule is that multiplying or dividing an inequality by a positive number preserves its direction. Start with x/5 > −1. Multiply both sides by 5, which is positive: 5(x/5) > 5(−1). This simplifies to x > −5, so option A is correct. No reversal is permitted because 5 is not negative. Option B reverses the sign incorrectly. Option C changes the negative boundary to a positive one, and option D combines an incorrect boundary with an incorrect direction. A quick check confirms the result: x = 0 satisfies x > −5, and 0/5 = 0 > −1. The boundary x = −5 is excluded because the original relation is strict; substituting it gives −1 > −1, which is false.
