This might be a bit off-topic, but I'm curious about something math-related. Usually, in algebra, we use 'x' as the independent variable in equations. Is this always the case, or are there situations where 'x' can represent a dependent variable instead?

There's no strict rule that 'x' must always represent the independent variable in an equation. While it is a common convention to use 'x' as the independent variable and 'y' as the dependent variable in algebra and coordinate geometry, you may find situations where 'x' can represent a dependent variable.

For example, in parametric equations, both 'x' and 'y' are dependent variables and are expressed as functions of a third parameter, usually denoted by 't'. The usage of variables in equations can vary depending on the context or subject matter, like in physics or engineering, where particular symbols are used to represent distinct variables.

So, while it's a widespread convention to use 'x' as the independent variable, there's nothing preventing you from using it as a dependent variable should the need arise, as long as the relationships between the variables in the equation are clear and well-defined. Just make sure to be consistent in your notation and ensure that the readers are able to understand your choice of variables.
