Which best proves why the expressions 4 (x + 3) + 2 x and 6 (x + 2) must be equivalent expressions?
When x = 3, both expressions have a value of 30.
When x = 5, both expressions have a value of 42.
When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60.
When x = 2, both expressions have a value of 15, and when x = 6, both expressions have a value of 39.
An equation, or, perhaps an equality. 5X - 5 = 20 this equation has the same value that will satisfy it, with some manipulation this is two expressions having the same value 10 - 6 = 2 + 2
what you might be searching for is an equation. I can't really tell by the grammar of the question.
No, expressions cannot have the same value in algebra. They may be assigned to different values and on solving we can get different answers in each case.
Equivalent Expression
An equivalent expression.
None of "these" expressions represent anything!
In mathematical expressions, a variable (a letter used to represent a certain value) represents an unknown or changeable value. It is often the variable x.
They are identities.
They are equivalent fractions.
An expression that represents a numeric value. Other types of expressions can represent character or Boolean values.
Equivalent expressions.

They are called: Identical equations or IdentitiesSee: http://www.tutorvista.com/search/value-algebraic-expressions-33 - -7 = ss = -26
Any "expression" that represents a numeric value. Example: 2+2=4 or x+7=10. Actually the examples above are equations, not expressions. Expressions do not have = signs. 7a and 4x are examples.
two expressions that have the same value for all allowable replacements are called equivalent.
