WebTo solve linear simultaneous equations with two variables by graphing, plot both equations on the same set of axes. The coordinates of the points at which the two lines intersect are the solutions to the system. What are Simultaneous Equations? Simultaneous equations are a set of equations that are solved at the same time.

The next step is to add these together: 2 x 2 + 8 x + 5 x + 20 is the same as 2 x 2 + 13 x + 20. So the original equation (2 x + 5) ( x + 4) = 0 becomes: 2 x 2 + 13 x + 20 = 0. This type of equation is known as a quadratic equation. There is more on this below.
