Question

'To a number, add another and then subtract this sum from the first number' is algebraically written as

• A. $x-(x-y)$
• B. $x-(x+y)$
• C. $(x-y)+x)$
• D. $(x+y)-x$

Answer 1

The correct option is B

$x-(x+y)$

To a number $x$(say), we add another number $y$(say).

Then the sum of these two numbers is $x+y$.

Subtracting this sum from the first number is algebraically written as '$x-(x+y)$'.

Hence 'To a number, add another and then subtract this sum from the first number' is algebraically written as '$x-(x+y)$'.
