Since there are two unknowns, there must be two equations. Let y be the amount that Bob has.Īlways let x and y answer the question - and be perfectly clear about what they represent! Let x be the amount of money that Andre has. While if Bob gave Andre $22, Andre would then have twice as much as Bob. If Andre gave Bob $20, they would have the same amount. This carefully selected compilation of exam questions has fully-worked solutions designed for students to go through at home, saving valuable time in class.H ERE ARE SOME EXAMPLES of problems that lead to simultaneous equations.Įxample 1. Only this one is for quadratic equations.Ģ0 | Linear simultaneous equations GCSE 9-1 exam question practice This carefully selected compilation of exam questions also has fully-worked solutions designed for students to go through at home. This PowerPoint for simultaneous equations is specifically for the elimination method, but also briefly covers the substitution method.Ģ1 | Quadratic simultaneous equations GCSE 9-1 exam question practice There are three sets of linear simultaneous equations for students to correct and a linear/quadratic to look at.Ģ2 | Solving simultaneous equations with the elimination method in KS4 Answers are included.Ģ3 | Correcting errors in linear simultaneous equations worksheetĬlumsy Clive is tackling simultaneous equations homework but as per usual is making errors. This worksheet features 12 simultaneous equation questions for students to solve graphically.
There is a mini-plenary and plenary embedded, and answers are provided throughout.
The main and extension are grade B questions. The starter recaps work on solving equations. This is a three-part lesson on solving simultaneous equations where the coefficients of one variable is the same. The starter is a kinaesthetic activity where pupils order themselves according to the value of the expressions they are holding (answers and values to substitute are shown on the board).įor the main activity they pick out graphs to find pairs of solutions to (at first by trial and error) – which later they draw and solve graphically.Ģ5 | KS4 introductory lesson to solving simultaneous equations This full lesson introduces solving simultaneous equations using graphical methods. 26 | Simultaneous equations and graphs lesson
