It can be: 2x-25 or 25-2x or maybe the absolute value of (2x-25).
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.

A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)

To find the value of an algebraic expression is to evaluate it.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
When the value of a variable in an algebraic expression changes, the value of the expression can change.

The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.

Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
Absolute value can be defined as the distance from the expression to zero. Therefore, the absolute value of 13 is 13.
addition
If y = 3 then what is the value of: y + 8 = ? a number equal eight
