प्रश्न
By how much does 1 exceed 2x − 3y − 4?
उत्तर
To calculate how much does 1 exceed 2x-3y-4, we have to subtract 2x-3y-4 from 1.
Change the sign of each term of the expression to be subtracted and then add.
Term to be subtracted = 2x-3y-4
Changing the sign of each term of the expression gives -2x+3y+4.
On adding:
(1)+(-2x+3y+4 )
= 1-2x+3y+4
= 5-2x+3y
