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.

To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...

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 ...
