A and C are both variables.
Letters used in math are called variables.
In math, the purpose of Cramer's rule is to be able to find the solution of a system of linear equations by using determinants and matrices. Cramer's rule makes it easy to find a system of equations that have many unknown variables.
it is the something
Independent variables are the input value of a function (usually x) and dependent variables are the output value of the function (usually y).
You isolate variables in math because the point of an equation is to solve for the variables. By isolating the variables you have learned what that variable stands for and thus solved the equation.
those words either mean math or science words
Variables
A and C are both variables.
Independent and dependent are types of variables. These variables are used mostly in science and math. When using independent variables you can control them dependent variables you cannot.

Because they allow you to generalise results. Then, for specific value of the variables you get specific answers.

By inserting the known quantities into their respective variables.
