Solution
an solution
The LHS expression = RHS expression
It is the solution or root of the equation.
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.
Such a value is called a "solution" or "root" of an equation.
Such a value is called a "solution" or "root" of an 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.
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.
Such a value is said to be a solution, or a root, of the equation.
Solution
an solution
Substitute that value in the equation, and then check to see if the resulting statement is TRUE.
That's the "solution" of the equation.
You call that a "solution" of the equation.
solution
The Solution of an equation is the value of the variable that makes the equation truean answer
