Sed question to substitute data in \2

Hi All,
Here is what I'm trying to do with sed:

Input File:
Code:
somechangeVariable1=Something I would like to change
somechangeVariable2=Something else I would like to change
...

Output File:
Code:
somechangeVariable1=Something I would like to different
somechangeVariable2=Something else I would like to different
...

So I tried this unsuccessfully in sed:
Code:
/\(.*\)=\(.*\)/{
	/\2/ s/change/different/
}

Error:
Code:
line 2: Invalid back reference

Question:
How do I run the substitute on \2 alone?
I realize that I can use other tools but would like to solve this with sed as more of a theoretical exercise at this point.

Thanks in advance for any help provided.
Peace!
