How do you find the value of an algebraic expression?
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
How do you evaluate an algebraic expression when I know the value of each variable?
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
What kind of symbol that is usually letters which represent a value or a number?
It is an algebraic variable.
How do you find a specific numerical value for an algebraic expression?
you have to deduce the variable and evaluate the expression.
Two algebraic expressions are if they have the same value for all values of their variable?
They are identical or equivalent.
A solution is the value(s) of the variable that makes the algebraic sentence?
equal
How can you have different values in algebraic expressions?
When the value of a variable in an algebraic expression changes, the value of the expression can change.

What is the value for a variable that makes an equation?
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.
What the vaule of x?
x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
