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 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 ...

This KS3 or GCSE PowerPoint activity has a couple of simple slides showing what we mean by solving simultaneous equations, and how to solve them graphically. There are some questions and answers at ...
