Simultaneous equations like 𝒚 = 2𝒙 - 1 and 𝒚 = 𝒙 + 1 can be represented graphically. To solve the equations graphically, the two lines 𝒚 = 𝒙 + 1 and 𝒚 = 2𝒙 - 1 are drawn on the same diagram.

The unknown values in an equation could be the individual costs of a smoothie and a banana when the combined cost is known. Simultaneous equations can be useful when running a business. Watch the ...

During lockdowns, I researched viral internet maths sensations. Several of them are what a teenager might recognise as simultaneous equations. In the emoji example above, smiley faces = 4 and blown ...
