Answer 1

Answer:

x = -1/2

y = -9/2

Step-by-step explanation:

x + y = -5 - (1)

x -y = 4 - (2)

Adding 1 and 2

2x = -1

x = -1/2

Putting value of x in (1)

-1/2 + y = -5

y = -5 + 1/2

y = -10 + 1 / 2

y = -9/2

Answer 2

Ans.(a)

Let a and b the two integers

$⇒a - b = - 5$

Now,

$\textbf{Let} \: 1 - b = - 5$

$⇒b - 1 + 5 = 6$

$∴a = 1,b = 6$

Hence, the pair of integers is a 1 and 6.

Ans.(b)*

$⇒8 - 4 = 4$

There

the two integers a,b are

a = 5 , b = 3 then

a-b
