To determine if the expressions (5x - 3xy - 5x) and (7xy - 4y) are equivalent, we can simplify the first expression. Simplifying (5x - 3xy - 5x) results in (-3xy). The second expression, (7xy - 4y), does not simplify to (-3xy). Therefore, the two expressions are not equivalent.
If you mean: 5(x-4) = 5x-20 then both expressions are equivalent
It means to replace an expression by another one that is equivalent, but simpler. For example: 3x + 5x can be written as: 8x because of the distributive property.
To determine if (2(6-3x) + x) is equivalent to (2(3x) + x), we can simplify both expressions. Starting with the left side: (2(6-3x) + x = 12 - 6x + x = 12 - 5x). Now for the right side: (2(3x) + x = 6x + x = 7x). Since (12 - 5x) is not equal to (7x), the two expressions are not equivalent.
Two expressions on both sides of the equal sign are equivalent to one of them changing sign when switched over to the other side. For instance: 5x = 3x + 10 Is equivalent to: 5x - 3x = 10 That means that you can very well "combine" them, if you don't forget to switch the sign. As it were, you would be switching it over and combining in a single step.

Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).

25xy is an equivalent expression.
25x+20y=5x(5+4y)
yes, 5x is a expression. A expression in algebra does not contain a = sign. a = sign means its an equation. A algebraic equation is built out of expressions.

An expression can have multiple outcomes, such as 5x+2, whereas an equation is a pair of expressions that equal each other, and can be solved, like 5x+2=12.
