We solve an equation by working out the value for one letter. To solve an equation we use the inverse operations to undo the equation. This video shows a visual method for solving a word problem. The ...

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 = ...
