What is the solution of (11-2(5-x)>3x+4)?

Answer and explanation

Correct answer: \(x<-3\)

Simplifying the inequality gives \(11-10+2x>3x+4\), or \(1+2x>3x+4\). Subtracting \(2x\) gives \(1>x+4\), and subtracting 4 gives \(-3>x\). Hence, \(x<-3\) is the correct solution. The close distractor \(x\leq -3\) is incorrect because the inequality is strict: at \(x=-3\), both sides are equal, so this value is not included. Exam tip: Reverse an inequality sign only when multiplying or dividing by a negative number.
