Simultaneous differential equations are no different; in order to find out the solutions to a series of differential equations, plot both graphs on the same x-y axis.

Find out how to solve simultaneous equations using a graph in this Bitesize KS3 maths video.

Simultaneous equations can be solved algebraically or graphically. Knowledge of plotting linear and quadratic graphs is needed to solve equations graphically.

Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. Linear equations allow you to predict values within your data set and view the overall trend.
