Sum and Difference of Numbers

The two numbers are +4 and -4 whose sum is 0 and difference is 8

Step-by-step explanation:

Let the two numbers be x and y .

Then

x + y = 0; ------- (1)

and

x - y = 8; ------- (2)

Adding the two equation,

x + y = 0;

x - y = 8;

------------

2 × x = 8

⇒ x = 8/2

⇒ x = +4

Subtracting (2) from (1)

⇒ 2 × y = -8

⇒ y = -4

Hence, the two numbers are +4 and -4 whose sum is 0 and difference is 8
