When isolating a variable, you want to get the variable alone on one side of the equation and then what it equals on the other side. Anything you do to one side of the equation, you must do to the other. e.g.
3x+2=8
First, you subtract 2 from both sides leaving:
3x=6
Then you divide both sides by 3, and you are left with: x=2
Yes, that is what you are normally required to solve for.
In a math problem, "left" typically refers to the direction on a number line that is less than or before a given point. When solving equations or working with expressions, moving to the left usually involves subtracting or dividing to simplify or isolate variables. The concept of "left" in math is relative and depends on the context of the problem being solved.
A and C are both variables.
Letters used in math are called variables.

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.

Variables
A and C are both variables.
those words either mean math or science words
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.

To replace a number in an equation
Independent variables are the input value of a function (usually x) and dependent variables are the output value of the function (usually y).
