Which of the following is the solution of the inequality \(4(x+2)-3(x-5)\geq 20\)?

Answer and explanation

Correct answer: \(x\geq -3\)

Expanding the brackets gives \(4x+8-3x+15\geq 20\), so \(x+23\geq 20\). Subtracting 23 from both sides yields \(x\geq -3\), making option A correct. Option B reverses the inequality incorrectly, while options C and D result from an incorrect subtraction. Exam tip: when removing a minus sign before a bracket, change the sign of every term inside that bracket.
