Variables are just letters to solve for the unknowns.
ex of a variable:
4x-6 = 16
x is a variable in this case, so we solve for it
4x = 22
x = 11/2
The variable is d, in the algebraic expression 7d+2
Of course! that is the objective of the algebraic expression, isn't it?
An expression with a variable.
Yes. That is the definition of an algebraic expression.
Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
An algebraic expression is a type of expression that contains a variable or variables.
An algebraic expression is a type of expression that contains a variable or variables.
It is the coefficient of the variable
A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.
The unknown variable in the expression: 6n+3 is n
When the value of a variable in an algebraic expression changes, the value of the expression can change.
The variable is "d".
