Find the solution set of x/4 + x/6 ≤ 5.

Answer and explanation

Correct answer: x ≤ 12

The least common denominator of 4 and 6 is 12. Multiplying the entire inequality by 12 is valid because 12 is positive, so the inequality sign remains unchanged: 12(x/4) + 12(x/6) ≤ 12·5. This gives 3x + 2x ≤ 60, hence 5x ≤ 60. Dividing by positive 5 yields x ≤ 12. Therefore option A is correct. Equality is allowed because the original sign is ≤; indeed, x = 12 gives 12/4 + 12/6 = 3 + 2 = 5. Option B reverses the direction, option C wrongly excludes x = 12, and option D comes from adding the denominators or otherwise mishandling the fractional coefficients. The solution set is (−∞, 12].
