Simultaneous equations - Higher
Solving simultaneous equations using a graph is easier than you might think. First, you need to draw the lines of the equations. The points where the lines cross is the solution.
The graphs of linear equations will give straight lines.
For example, to draw the line 2x + 3y = 6 pick two easy numbers to plot. One when x = 0 and one where y= 0
In an exam, only use this method if you are prompted to by a question. It is usually quicker to use algebra if you are not asked to use graphs.
