The main rule is that whatever rule you perform on one side of the equation must also be performed on the other side of the equation. You have to choose the operation in such a way as to isolate the variable you want to solve for.
In algebra whereas x is usually the unknown variable to be solved.

You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
A variable is assigned to represent an unknown quantity.
The answer is variable

If you mean a variable then it is an unknown quantity that can represent many values until its specific value is determined usually by solving an equation.
A variable is usually assumed to represent an unknown quantity. You don't need to "do" anything special to your variable.
Equations are used to find the solution to the unknown variable.
