I can’t figure out what I’m doing wrong. I just want to replace the equals sign with an inequality sign. Thanks in advance.

I’m not sure if that works with symbols or operations… I can only get it to work with variables and constants. Here is a workaround for a single equal sign. I’m not sure about how you would replace multiple equal signs. [Copy of] delete substituteLatexVariable • Activity Builder by Desmos

Yeah, that’s the workaround I ended up using. It was a little tedious for my actual use case but it worked.
