We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions. or \(x=100 ...

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.

with B * = I- B. This requires that one of the preceding equations be solved for P t. Solving the second equation for P t yields You can estimate the intercepts of a system of simultaneous equations ...

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 ...
