You can check for a few numbers, to see whether they give you the same result. This quick check can save you lots of work in the following step, in the case of complicated expressions: if, when replacing by some number, the two expressions are NOT equal, then of course they are not equivalent.However, the variables can usually have infinitely many values (Boolean algebra is an exception), in which case the only way to prove that two expressions are equivalent - meaning, equal for ALL values of the variable or variables - is to try to do some equivalence transformation to one expression, to convert it to the other expression.
Two expressions that are equal are called "equivalent expressions." These expressions yield the same value for all values of their variables. In mathematics, this concept is essential for solving equations and simplifying expressions.
These two are both similar because they are both expressions.
That means that the two expressions represent the same number.
A quotient.

when a symbol such as <or> is placed between two expressions
When two expressions are equal they can form an equation.
when a symbol such as <or> is placed between two expressions
the answer is a(n) equationequationWhen two expressions are equivalent they can form an equation.
These two are both similar because they are both expressions.
A statement that equates two equivalent expressions is called an Identity.
If two mathematical expressions are equal then they form an equation.
That means that the two expressions represent the same number.
An equal sign (=) with a slash through (/) represents that two expressions are disproportional.
