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.
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.
An unknown in an algebraic expression is a variable that represents a value we do not yet know. It is typically denoted by letters such as (x), (y), or (z). The purpose of the unknown is to allow for the formulation of equations and the exploration of relationships between quantities. Solving the expression involves finding the value of the unknown that satisfies the equation.
A number that one is solving for-the unknown.

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.
A variable is assigned to represent an unknown quantity.
The independent variable is the variable that is unknown until the experiment is performed. This is the variable that is manipulated by the researcher to observe its effect on the dependent variable.
