TopicInequalities
TypeSolve linear inequality
DifficultyEasy -1.8 This is a straightforward one-step linear inequality requiring only collecting like terms and dividing by a positive coefficient. It's a routine algebraic manipulation with no conceptual difficulty, significantly easier than a typical A-level question which would involve multiple techniques or problem-solving.
Spec1.02g Inequalities: linear and quadratic in single variable

1 Solve the inequality \(2 x + 5 < 6 x - 3\).

Question 1:
AnswerMarks Guidance
AnswerMarks Guidance
e.g. \(2x - 6x < -3 - 5\)M1 (1.1a, 1.1) Rearrange to get x terms on one side; number terms on other. Allow one sign error; allow one arithmetic error, allow wrong inequality (or equality) sign for M1. Expect to see \(4x > 8\)
\(x > 2\)A1
