certified best method (working 2025) (unpatched)


soooo 4/3 is the only solution? the teacher is wrong? omg

Technically yeah but seeing as the papers already been released it’s probably too late to change. In the hsc they would probably require you to sub k back in and test if the simultaneous has a solution or not but that’s such a sac

i reckon it could be 4 marks if so instead of 3
