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.
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.
