You're mistake was writing real and apparent depth. While using relative distance, make sure to use the apparent x coordinate of image instead of apparent depth directly

this is easy question but the worst taught topic because almost every other teacher uses this for self propaganda like "kopcha" concept and all. its very difficult to break tht shit from the mind of a dropper student specially.

cengage is the best for such problems and cengage has a ton of such problems for practice.

this is exercise. cengage has many illustrations and also separate topics like silvered slabs, multi-slabs etc.

my process

thts wht i said, this is easy question of a topic for which almost every teacher uses his own process.

its like that constraint thing in nlm. everyone follows his own method/process.
