Equations that have more than one unknown can have an infinite number of solutions. For example, \(2x + y = 10\) could be solved by: \(x = 1\) and \(y = 8\) \(x = 2\) and \(y = 6\) \(x = 3\) and \(y = ...

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 ...
