Simultaneous equations like 𝒚 = 2𝒙 - 1 and 𝒚 = 𝒙 + 1 can be represented graphically. To solve the equations graphically, the two lines 𝒚 = 𝒙 + 1 and 𝒚 = 2𝒙 - 1 are drawn on the same diagram.

This lesson will show students how plotting two linear equations in x and y allows them to solve simultaneous equations. The PowerPoint has a full explanation as the starter and there is a sheet of ...

The first two sections fit onto two sides of A4 and part 3 is the extension. There is also an answer sheet. There is a RAG table for students to mark their progress. You can amend this depending on ...

Abstract: Simultaneous nonlinear differential equations of growth of two variables x and y with time can be readily solved graphically by a method in which two directrices are used in the ...
