This Simultaneous Equations lesson gives students a thorough grounding in solving pairs of equations with two unknowns, such as y − 2x = 9 and x + y = 5. Across 31 slides, students are shown both the algebraic method and the graphical method for solving simultaneous equations, so they understand not just how to reach an answer but what that answer represents.
The lesson goes further than a single method, also covering simultaneous linear and quadratic equations, and finishing with word problems that require students to set up their own pair of equations from a written scenario before solving them.
By the end of the lesson, students will be able to solve simultaneous equations algebraically, solve them graphically, solve simultaneous linear and quadratic equations together, and solve word problems that lead to simultaneous equations — a comprehensive set of GCSE-level algebra skills in one resource.
Covering both the algebraic and graphical approaches side by side helps students see simultaneous equations as one connected idea rather than two unrelated methods to memorise separately, which is often where confidence breaks down at GCSE.
Every question is self-marking with instant feedback, making this lesson suitable for first teaching, consolidation or focused exam revision.
