a solution
It is called the "soulltion set"
a variable
You substitute the value of the variable into the equation and simplify. If the rsult is a true statement then that value of the variable really does satisfy the equation.
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
It is an identity.
It is called the "soulltion set"
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
It is the solution of the given equation.
A two-step equation is a mathematical equation that requires two steps to solve. It involves applying inverse operations to isolate the variable on one side of the equation. The goal is to determine the value of the variable that satisfies the equation.
a variable
legal equation * * * * * In mathematics, it is called an identity.
Such a value is called a "solution" or "root" of an equation.
Such a value is called a "solution" or "root" of an equation.

linear equation in one variable
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
