Need logic help.

Question - "How do I do x?"

Answer - "y"

Question - "How do I do y?"

Answer - "z"

y =/= z

Is this valid?

Is this valid?

Yep. Y is not necessarily equal to Z in this case.

It could be, but it's not necessarily.

"How do I fix my door so it doesn't squeak?"

"Get some grease and oil the hinges."

"How do I get some grease and oil the hinges?"

"Go to the hardware store."

It could be equal to Z, if the person in question explained the entire thing en toto, but obviously 'Go to the hardware store.' is not the answer to 'How do I fix my door so it doesn't squeak?'

[MarginOfError]

You could write the statement

x => y AND y => z.

Notice that the statements are implications, not equivalencies.

Habla Ingles?

[Blackmarch]

Is this valid?

not enough info to only use logic to make that inference.

perhaps

Y = or =/= Z

edit... or what MOE wrote

Thanks. Precisely what I needed.
