Match the expressions with thier equivalent equations in the columns.

Question

List A: List B:
6x+12 6(1+x)
6+6x 6x-6
6(x-1) 6(x+2)
Fill in the blank:
The expression 6x+12 is equivalent to the expression __________
The expression 6+6x is equivalent to the expression __________
The expression 6(x-1) is equivalent to the expression __________

Noted:
So, I don't understand this because the problem is not saying what is variable x is, ( for example, y= 5, n=3 or b=8) *something like that*.
So, I don't know how to solve it or how to answer this problem. I also need help with the fill-in the blanks since i first don't know how to solve the expressions above.

Note: If anyone can help, that would be appreciated.

What I need from you:
- explaining (first)
on how to solve this problem
*this would also help a lot when I come across a problem (hopefully, in the future) like this then I am already prepared to solve the problem*
- answers (goes with explaining as well)
*to see the correct answers of the expressions (in the lists A and B)
and the fill-in blanks*

Note: If you don't understand on what I am asking then hopefully I can explaining it better to you when I respond back. (or read carefully on what I am saying and asking)

Own Words:
Sorry for asking too much but this will help me a lot.

In conclusion:
Thanks for helping!

Answer 1

Also the expressions are List A is seperated from expressions on List B.
Sorry for puting the lists all together but I hope you understand.

Answer 2

No value for x is needed. This is an exercise in recognizing the distributive property.

5(x+3) = 5*x + 5*3 = 5x+15

Now see what you can do.

Answer 3

Oh thanks! Now, I get it and thanks for the help. I can do this on my own now.

Answer 4

*sorry* my name is nathaly but I like to put my name shorter for nat...
