Simultaneous Equations | OCR GCSE Maths Higher | 40 Worked Examples (J560)

Simultaneous equations for OCR GCSE (9-1) Mathematics Higher tier (J560). 40 exam-style questions with fully worked, mark-scheme-annotated solutions: solving two linear equations by elimination and substitution, worded set-up problems in context, linear-quadratic pairs solved algebraically, the specification’s line-and-circle case (x^2+y^2=50 with 2y=x+5), solving by the quadratic formula, graphical intersection of a line and a curve, tangency by the discriminant, and reasoning about parallel lines with no solution or infinitely many. Progressive Easy to Challenging difficulty. Every working line is annotated, with OCR M/A/B marks folded in on the real mark-scheme lines, including the M2 factorising cascade OCR uses. Built for OCR’s no-formula-sheet exam, so the pack opens with the quadratic formula and the discriminant facts you must recall from memory. Calibrated against OCR J560 past papers and mark schemes (spec 6.03c and 6.03d), not ported from another board. Ideal for revision, homework, and 1-1 tuition.
