To substitute a value for each variable in the expression and simplify the resulting numerical expression?
It is unknown for right now.
What is characteristic of coefficient?
A coefficient has a fixed value, unlike a variable in an expression.
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!
To solve a system of equations you cannot replace a variable with an equal value or expression?
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.
What does it mean to evalutate the expression?
Replace each variable in the expression by its value and then find the value of the expression.
What is to replace a variable with a number or anotherexpression in an expression?
The term for replacing a variable with another value or expression is "substitution."
Is a variable a variable expression?
Yes. A variable by itself, or anything that contains a variable, would be a variable expression (unless the variable cancels out, as in "x - x", which always has the same value).
Can you solve for the value of a variable in an expression?
Yes
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.
How do you evaluate the expression P86?
If it is a variable-name, then just fetch the value of the variable.
What does varable expression mean?
A variable expression is an expression which contains variables(symbol that represents a certain value). For example, 4a-90. 4a-90 would be the expression an a is a variable
How do you find a specific numerical value for an algebraic expression?
you have to deduce the variable and evaluate the expression.
What can change the value of an expression in math?
A change in the coefficient, a change in the value of a variable.
What is to find the value of a numerical or algebraic expression?
to solve for the variable
