Introduction to Simultaneous Equations
Key Stage: 3 ★
Each shape in the grid has a numerical value, and the totals of the rows and columns are shown. Can you find the total of the missing column?
This problem provides a good challenge in reasoning working with multiple unknowns. There are issues of redundancy to think about in the provision of too much information. This is a pre-algebra task that can introduce students to the sort of manipulations that can be used to solve simultaneous equations.
This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.
