What a simultaneous solution means

What a simultaneous solution means

Graph of the lines 2x + y = 7 and x - y = -1 crossing at the solution point (2, 3)

Each linear equation is a straight line, and the simultaneous solution is the point where the lines cross. A solution pair must make both equations true at the same time.

Step-by-step lessons covering Oxford AQA IGCSE Maths Simultaneous Equations for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
