Question

A whole number is added to 69 and the same number is subtracted from 69. Find the sum of the resultant numbers

Answer 1

Answer:

The sum is 138

Step-by-step explanation:

Given that a whole number is added to 69 and the same number is subtracted from 69.

we have to find the sum of the resultant numbers.

Let the number which is added and subtracted is x.

The number when added to 69 the resultant will be

69+x  → (1)

The number when subtracted from 69 the resultant will be

69-x   → (2)

Adding expression (1) and (2), we get

$69+x+69-x=69+69=138$
