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 ...

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 ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

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 ...

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 ...
