Which is the solution of 18 < 6x?

Answer and explanation

Correct answer: x > 3

The governing concept is isolating the variable in a linear inequality while preserving its direction. From 18 < 6x, divide both sides by 6, which is positive. This gives 3 < x. Rewriting the same relationship with x first gives x > 3, so option A is correct. Since the divisor is positive, the inequality sign does not reverse. The endpoint x = 3 is not included because the original relation is strict: 18 is not less than 18. A value such as x = 4 gives 18 < 24 and works, while x = 2 gives 18 < 12 and fails. Options B reverses the sign without justification, and C and D incorrectly add rather than divide by the coefficient 6.
