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.

What property that justifies 5 times bracket x-4 bracket equals 5x-20?
If you mean: 5(x-4) = 5x-20 then both expressions are equivalent
What is a mathematical sentence that contain an equals sign that shows that two expressions are equivalent?
A mathematical sentence that shows two expressions are equivalent is an equation, such as (5x + 3 = 18). This sentence states that the expression (5x + 3) is equal to the expression (18) for certain values of (x). Additionally, another example could be (2(a + b) = 2a + 2b), demonstrating that both sides represent the same value when simplified.
What does simplify variable expressions mean?
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.
Is 2(6-3x) plus x equivalent to 2(3x) plus x?
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.
Why can't you combine like terms across equal signs?
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.
