An equation if both expressions are equal
That means that the two expressions represent the same number.
equivalent
You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.
equation

the answer is a(n) equationequationWhen two expressions are equivalent they can form an equation.
equivalent expressions
A statement that equates two equivalent expressions is called an Identity.
