If (x/2) − ((x−3)/4) > ((2x+5)/8), what is the solution?

Answer and explanation

Correct answer: All real numbers

The correct answer is D: all real numbers. Multiply the entire inequality by 8, which is positive, so the inequality sign does not change. We get 4x − 2(x − 3) > 2x + 5. Expand the left side: 4x − 2x + 6 = 2x + 6. Therefore 2x + 6 > 2x + 5. Subtracting 2x from both sides gives 6 > 5, which is always true. Hence every real value of x satisfies the inequality. Option A includes only numbers below 1, so it misses valid values such as x=2. Option B includes only numbers above 1 and misses x=0. Option C is similarly too restrictive. Option D is correct. Memory cue: multiplying by a positive number preserves the sign; a true statement independent of x means all real numbers are solutions.
