Question

Integers whose difference is 16.and sum is -63

Answer 1

Answer:

The integers are -23.5 and -39.5

Step-by-step explanation:

let the need integer be x and y

and x>y

According to the qn,

(i) x - y= 16

(ii) x + y= (-63)

Add the equations (i) and (ii)

(x - y) + (x + y) = 16 + (-63)

x - y + x + y = 16 -63

2x = - 47

x = -23.5

therefore,

y = x - 16

y = -23.5 - 16

y = -39.5

Answer 2

Answer:

x = -23.5

y = - 39.5

Step-by-step explanation:

let the integers be  x and y

          x + y = -63

+        x -  y =  16        

        2x = -47

         x = -47÷2

        x = -23.5

x + y = -63

-23.5 + y = -63

y = -63 + 23.5

y = - 39.5

[ x + y = - 23.5 + (- 39.5) = -23.5 - 39.5 = - 63.0]

[x - y = -23.5 - ( -39.5) = -23.5 + 39.5 = 16]
