Equivalent expressions are expressions in algebra that are equal in value, even though they look different. Equivalent expressions will have the same value when we use the same value(s) for the variable(s).
Two expressions are equivalent if they have the same value for any possible substituted value(s) of the variable(s) involved. We use the symbol \; \equiv \; to show that two expressions are equivalent. For example, the equation 3x+2=14 is only true for one value of x, i.e. x=3.

Algebraic expressions, such as 4x+3y-2w^2, 4x+3y −2w2, contain variables, numbers, and mathematical operations. Algebraic expressions may be written in different ways, but still mean the same thing. For example, the expressions r+r+r+r \text { and } 4r r +r +r +r and 4r. are equivalent.
18 gru 2023 · Equivalent algebraic expressions are algebraic expressions that are equal in value but look different. Thus, if we have two algebraic expressions and they yield the same value for every possible substitution of the variables, then they are considered equivalent.
4 lip 2020 · Equivalent Expressions Equivalent Expressions are expressions that have the same value. They may look different but will have the same result if calculated. For example, and are equivalent expressions. See why below: The two expressions have the same answer, 27. Therefore, we can say that they are equivalent expressions.
