Simultaneous Equations, Years 9–11
Two draggable lines show a live intersection calculation, including parallel, coincident and perpendicular cases, alongside the working for elimination and substitution. The full interactive is available to licensed Education Universe users.
Years 9–11Explorer
Learning outcomes
- Interpret the solution of simultaneous equations as an intersection.
- Solve simultaneous equations by elimination and substitution.
- Recognise systems with no solution or infinitely many solutions.
Teaching guidance
Ask students to solve a system algebraically first, then confirm the result graphically.
