Answer:
1/18+1/x=1/12
1/x=1/12-1/18
1/x=18-12/18*12
1/x=6/216
1/x=1/36
Therefore x=36

Answer:
the total work will take 21 days.
Step-by-step explanation:
A can finish a work in 12 days and B can finish that work in 18 days. Now, A left the work 3 days earlier and now B was all left alone. So, he could have finished the work in 18 days but as A left 3 days earlier. So, B had to finish the work all alone and therefore, he took more 3 days to complete and the total work took(18+3) days, so it took him 21 days to complete that work.
