To learn about Systems of Equations please click on any of the Theory Guide links in Section 2 below. For students working from the Maths In Action text book the recommended questions on this topic are given in Section 3. Worksheets including actual SQA Exam Questions are highly recommended.

If you would like more help understanding **Systems of Equations **there are full, easy to follow, step-by-step worked solutions to dozens of AH Maths Past & Practice exam questions on all topics in the AH Maths Online Study Pack. Also included in the Study Pack are full worked solutions to the recommended MIA text book questions. Please give yourself every opportunity for success, speak with your parents, and subscribe to the** exam focused**** **Online Study Pack today.

**Systems of Equations**

This topic covers:

Gaussian elimination is used to solve systems of equations.

Elementary Row Operations (ERO’s) are used which alter the system to produce a new system with the same solutions.

- The order of the equations can be changed.
- An equation can be multiplied by a constant.
- One equation can be added to or subtracted from another.

To solve a system of equations we must convert the coefficient part of the augmented matrix to upper triangular form. This is where all the elements below the main diagonal (which runs from the top left to the bottom right) are zero

Not all systems of equations have a unique solution as in the equations below.

- x + y = 4
- 2x + 2y = 8

It can be seen that the second equation is just the first multiplied by two. Any values of x and y will therefore satisfy both equations. In this context, the second equation is **redundant** as it gives no additional information to the first.

Consider the equations below.

- x + y = 6
- x + y = 12

Since the second equation contradicts the first there are no solutions. In other words there are no values of x and y which satisfy both equations.

This occurs when a small difference in the coefficients of the equations causes a large change in the solution. In this context, we say that the system of equations is **ill-conditioned.**
