What this AA HL systems of linear equations worksheet covers

Solving systems of three linear equations in three unknowns, with unique, infinite and no-solution cases. The questions follow the order of the AA HL syllabus for Topic 1 (Number & Algebra) and are graded in three bands — routine practice, exam-standard, and the harder multi-step questions that separate a 6 from a 7.

Elimination and row reduction
Unique, infinitely many and no solutions
Geometric interpretation as planes
Solving with matrices and the GDC
Exam tip for this topic. When a system has infinitely many solutions, express the answer with a parameter (x = 1 + 2λ, …).

How to use it

  1. Do the first band without the AA HL formula booklet, then check which formulas you had to look up — those are the ones to memorise.
  2. Time the second band at roughly 1.2 minutes per mark, the pace of Paper 1 and Paper 2.
  3. Mark the third band against the solutions and rewrite every question you lost marks on from a blank page.
