It is done by substituting the values of the variables in the expression and then hope that you are capable of evaluating the result.
you have to deduce the variable and evaluate the expression.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
Evaluate using PEMDAS
Simplify !
Given a value of x, find the value for -3x + 2

To find the value of an algebraic expression is to evaluate it.
to simplify!!* * * * *No. It is to EVALUATE.

You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.

A term often used is "evaluate".

When the value of a variable in an algebraic expression changes, the value of the expression can change.
