An equation or an inequality that contains at least one variable is called an open sentence. ... When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.
Answer 1 == In an open sentence (an equation or inequality with a variable in it), when a number replacing the variable makes the sentence true, then it is a solution.
The root of any equation is a number which ... when substituted for the variable ...makes the equation a true statement.
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.
If A is a number that makes an equation true, then A is a "solution" to the equation.
That's the "solution" of the equation.
An equation can often be re-written so that the subject of the equation is changed. This makes it nonsense to define either variable as independent.
The Solution of an equation is the value of the variable that makes the equation truean answer
Such a value is said to be a solution, or a root, of the equation.
