Wheels - Simultaneous Equations

The inner and outer wheels combine to form 3 different equations. Turn the inner wheel to change the combinations and generate 3 different simultaneous equations in 2 variables. Find the wheel setting that solve consistently for the same values of a & b.

I’ve made each resource twice - once designed to be just printed and once where the inner wheels can be cut out and pinned to the outer wheels using paper fasteners (solutions can be found in the “cutting version”)

My main motivation in making this resource was to present a rich problem solving activity for the topic in a visually novel format.
