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 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.
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.

25xy is an equivalent expression.
What are some examples of equations and expressions?
25x+20y=5x(5+4y)
Is 5x an algebraic expression?
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.

When the expressions x2 9 and x2 5x plus 6 are factored a common factor is?
x - 3
What is difference between equation and expression?
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.
Is 3(3x 2y) equivalent to 5x 5y?
No
