Each linear equation can be drawn as a line on a graph. The co-ordinate where the two lines intersect will give the solution of x and y. STEP 2 - The equations can be rearranged so that they both ...

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 ...
