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.
In the equation x = 3, if x = 3, the equation is true, if x has any other value, it is not. The value of any other variable, such as y, is irrelevant. I would say that the answer is 0 because otherwise y is part of the equation which clearly it isnt.
Substitute that value in the equation, and then check to see if the resulting statement is TRUE.
solution
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.
Solution
an solution
Such a value is said to be a solution, or a root, of the equation.
solution
Such a value is called a "solution" or "root" of an equation.
That's the "solution" to the equation described by the sentence.
solve
It is the solution or root of the equation.
Such a value is called a "solution" or "root" of an equation.
linear equation in one variable
you have to solve the actual equation in order to answer this about your variable
