Subtract Measure Values from Column

[Niiru1]

Is there a way to subtract column values [Rules] from a measure?

My measure which gives me number of working days in a month is:

Measure 5 = 
VAR _Month = CALCULATE(COUNT(DimDate[Days in Month]),FILTER(DimDate,'DimDate'[WorkingDays] <>BLANK()))
VAR _lastday= 
COUNTROWS(
 FILTER(DimDate,'DimDate'[WorkingDays] <>BLANK()))
RETURN
 IF ( ISBLANK ( [AbsentByDay] ), BLANK (), _lastday )

Thanks,

@amitchandak I think I have it here:

Measure 9 = 

IF(HASONEVALUE('Employee Absence Full Table'[Rules]),[Measure 5],
SUMX(
ALLSELECTED('Employee Absence Full Table'),
[Measure 5]))- SUMX(ALLSELECTED('Employee Absence Full Table'[Rules]),'Employee Absence Full Table'[Rules])

But I end up with this, is there a way to just remove the values if measure 5 is blank?

@Niiru1 , The output will be measure not column.

Can you share output in table format?
