H2 + CO2 <--> H2O + CO

if there were something that were added to this system to absorb the CO2, where would the equilibrium shift? Please don't just give the answer, explain as well, thanks :)

How about a little of neither. Le Chatelier's Principle, in not so eloquent terms, says that the reaction will shift so as to try and undo what we've done to it. So if we remove CO (not CO2) from the reaction it will shift to add more CO back. Which way is that? If you said right you would be right(correct).
Now if you remove CO2, it will try to add CO2 to replace what we've removed. Which way will it shift?
left?
yes
