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
Equivalent expressions.
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.
4b-b
5.05 is equivalent to 5.05. No other number is equivalent, though you might write the number in different ways, i.e., using different expressions that evaluate to that number.

An equation if both expressions are equal
how many different ways can you use the digits 3 and to write expressions in exponential form/ what are the expressions
with a pencil and paper
In the same way that you would solve equations because equivalent expressions are in effect equations
