A verb ちがう and its indicators


I came across a task in which I had to complete different sentences by putting
correct case indicators. Everything seemed to be fine until I reached a
sentence which made me think a lot about what case indicator to put. So, the
sentence is this:

> 私の答えは山口さんの答え **(case indicator)** ちがいます。

At first I thought that と would be a good option because I saw this sentence
"私とちがう考えの人はいませんか". I'm not sure whether this is actually related to my
situation but it seemed to be a good enough. I also was considering ほど to be
put there but since it only can be used with a negative form of predicate,
this is not the option I need. Now I think that it's が but am not sure.

P.S. I'm having zero problems with comparative constructions that use より, の方,
etc. so far, but the one I mentioned above makes me ask a lot of questions.

P.S.S. I also would like to know what case indicators work with this verb and
their meaning.




I also asked for help on another [language exchange
forum](https://hinative.com/en-US/questions/12061520) and was told that the
sentence "私の答えは山口さんの答え **(case indicator)** ちがいます。" has to have と in it. That
being said, if I need to say that "A is different from B", I use the verb
違{ちが}う with case indicator と.

Here are some speech patterns:

1) AはB「と」ちがう。- A is different from B - この犬はあの犬と違う。

2) AとB「は」ちがう。- A and B are different - 犬と猫は違う。
