I assume you mean, in an equation. Such a number is called a "solution" or a "root" of the equation.
A solution or root makes a true statement when substituted in an equation.
The root of any equation is a number which ... when substituted for the variable ...makes the equation a true statement.
The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.
Each value of x, when substituted in the equation, will give a true statement.
always true
A solution or root makes a true statement when substituted in an equation.
Not if the statement is inexplicable in numerical terms, and not always when it is.
An example of a true statement in algebra is x=x
The number is called a solution.
Solution or a root

You call that a "solution" of the equation.
It means that whatever you have substituted is the solution of the given linear equation. Or you have substituted the equation in itself.
Each value of x, when substituted in the equation, will give a true statement.
The 'solution' of an equation is the number which, when substitutedfor the variable, makes the equation a true statement.You have said: [ x = 5 ] .We claim that the solution is '5', because when '5' is substituted for 'x',the equation reads5 = 5and that's a true statement.
No number, by itself, makes it true.
