What is the correct conclusion for (4(2x+3)>8x+15)?

Answer and explanation

Correct answer: No solution

Expanding the left-hand side gives \(4(2x+3)=8x+12\). Thus, the inequality becomes \(8x+12>8x+15\). Subtracting \(8x\) from both sides gives \(12>15\), which is false. Hence, the inequality is not true for any real value of \(x\), so there is no solution. Options such as \(x>3\) or \(x<3\) are incorrect because the variable terms cancel completely. Exam tip: When the coefficients of the variable are the same on both sides, cancel those terms first and compare the constants.
