How to find Equivalent Expressions Equivalent Expressions are expressions that are equal to each other even though they may look different. In math, this means that you can use substitution for the variable to get the same answer. For example, if you substitute the same value in for x into two expressions and you get the same simplified answer ...

Expressions can be equivalent for all values or only when specific values are used. To know if expressions are equivalent, when given a specific value for a variable, we substitute the value into the expressions and evaluate the expressions. To know if two expressions are equivalent for ALL values of a variable, we simplify the expressions to a ...

Algebraic expressions contain at least one variable. A variable is a letter of the alphabet that takes the place of an unknown amount. The terms of an expression are separated by + and -. A coefficient is a number directly to the left of a variable, which indicates multiplication. The + and - before each term belongs to that term. Like terms ...
