Simultaneous EquationsA selfmarking, multilevel set of exercises on solving pairs of simultaneous equations. 
This is level 6: equations which include fractions in some way. You will be awarded a trophy if you get at least 9 correct and you do this activity online.
InstructionsTry your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help. When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file.

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 14 October 'Starter of the Day' page by Inger Kisby, Herts and Essex High School: "Just a quick note to say that we use a lot of your starters. It is lovely to have so many different ideas to start a lesson with. Thank you very much and keep up the good work." Comment recorded on the 7 December 'Starter of the Day' page by Cathryn Aldridge, Pells Primary: "I use Starter of the Day as a registration and warmup activity for my Year 6 class. The range of questioning provided is excellent as are some of the images. 
Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month. The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing. Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page.

Go MathsLearning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school. Maths MapAre you looking for something specific?

Projectable  A set of simultaneous equations designed to be shown one at a time to the whole class.
Level 1  Equations that can be added or subtracted to eliminate one variable.
Level 2  Equations that can be added or subtracted to eliminate one variable after one of the equations has been multiplied by a constant.
Level 3  Equations that can be added or subtracted to eliminate one variable after both of the equations have been multiplied by constants.
Level 4  Equations with two variables that are not written in the standard way.
Level 5  Real life problems that can be solved by writing them as simultaneous equations.
Level 6  Equations which include fractions in some way.
Level 7  Linear, quadratic and other pairs of simultaneous equations.
These Level 7 questions will require you to be able to solve Quadratic Equations.
Exam Style Questions  A collection of problems in the style of GCSE or IB/Alevel exam paper questions (worked solutions are available for Transum subscribers).
More Simultaneous Equations including lesson Starters, visual aids, investigations and selfmarking exercises.
There is a printable worksheet to go with this activity. It is an exercise that appeared in an algebra book published in 1895. It starts with basic questions but soon gets tricky!
Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.

The examples used in the video are available to teachers as projectable slides.
\(7x+ \frac{y}{2}=13 \qquad \mathbf{A}\\6x + \frac{y}{3}=10 \qquad \mathbf{B} \)
Multiply equation \( \mathbf{A} \) by 2 and multiply equation \( \mathbf{B} \) by 3.
\( 14x+y=26 \qquad \mathbf{C}\\ 18x+y=30 \qquad \mathbf{D} \)
Subtract equation \( \mathbf{C} \) from equation \( \mathbf{D} \)
\(4x=4\)
\(x=1\)
Substitute this value for \(x\) into equation \( \mathbf{A} \).
\(7 + \frac{y}{2}= 13\)
\(\frac{y}{2}=6\)
\(y=12\)
The simultaneous equations have been solved.
The solutions are \(x=1\) and \( y=12\).
You can check your answers by substituting them both into equation \( \mathbf{B} \) to see if it balances.
This example is not intended to teach you everything you need to know about this type of simultaneous equations. It is here as a reminder and is no substitute for your teacher or tutor.
These steps are developed and discussed in "How I Wish I'd Taught Maths: Lessons learned from research, conversations with experts, and 12 years of mistakes" by Craig Barton
