Is the expression $-12x - 18$ equivalent to the expression $-6x - 9 - 3(3 - 2x)$?

Question

Anonymous · Answer

-12x-18 and -6x-9-3(3-2x) 
 First, distribute the -3 into the parentheses. The second expression will turn out as such: -6x-9-9-6x. From here, you need to combine like terms (variables and numbers). -12x-18. So, yes, these two expressions are equal.

-12x-18=-6x-9-3(3-2x) -12x-18=-6x-9-9+6x -12x-18=-6x+6x-9-9 -12x-18=-18 -12x-18=-18 +18=+18 -12x=0 X=0

Anonymous · Answer

The expression − 12 x − 18 is not equivalent to the expression − 6 x − 9 − 3 ( 3 − 2 x ) since simplifying the second expression only results in a constant − 18 , while the first expression contains a variable term. Therefore, they do not produce the same result. The equivalency fails due to the presence of the variable in the first expression.
