Be careful to note what a GCSE question is asking. If it states ‘solve algebraically’ then you must do so. To find solutions from graphs, look for the point where the two graphs cross one another.

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 is a preview. Log in through your library . Abstract In our research in spectral graph theory we often encounter the need for the simultaneous editing of two or more interdependent graphs (e.g. a ...

Abstract: We define the concept of crossing numbers for simultaneous graphs by extending the crossing number problem of traditional graphs. We discuss differences to the traditional crossing number ...

Abstract: This article considers the dynamic event-triggered simultaneous fault detection and leader-following consensus (SFDLFC) problem for nonlinear multiagent systems (MASs) with directed graphs.
