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 ...

This PowerPoint shows the graphical methods for solving simultaneous equations using the cover-up method. Ben Cooper is a maths teacher in Birmingham. You can find more of his resources on his TES ...
