No.
A value that is unknown may not be a variable but simply a constant whose value needs to be calculated.
Solution
an solution
a "solution"
It is the solution or root of the equation.
No. The goal is to find a value of the variable(s) for which the solution is true. Getting the variable by itself is only a part of the process, not the goal.
True.
True
Yes, passing a variable by reference gives you a pointer to the original variable, meaning you can change its value from within the function being called and the change will affect the original variable.
If it does not change it isn't variable. The converse is also true.
the variable age has discriptive value but not necessarily explanatory value.
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.
linear equation in one variable
Maybe your speaking a variable that contains a ternary operators such as:
A variable does and must change, but you can only have one variable, otherwise the experiment becomes biased and unfair
A function assigns each value of the depend variable to more than one value of the inde variable is this true or false
