Question

step by step plz I will follow you who was say the answer step by step​

Answer 1

Step-by-step explanation:

Let negative consecutive integers= x and (x-1)

Their sum = -21

so,. (x) + (x-1) =-21

x + x -1 = -21

2x -1 = -21

2x = -21 + 1

2x = -20

x = -20 ÷ (2)

x = -10

Therefore first negative consecutive integer = x

= -10

second negative consecutive integer =

= x-1

= -10-1 = -11

Answer 2

-11;-12

Step-by-step explanation:

Two consecutive no.s can be obtained by taking a value variable and adding/subtracting it by 1

if even/odd condition is not given..

Let smaller no. be -(X)= -x (Putting a minus sign ensures it is a negative no. THIS IS OPTIONAL IN LOWER CLASSES)

Larger no is -(X+1)= -X-1

(-x)+(-x-1)= -21

-2x-1= -21

-2x= -21-1

-2x = -22

x = -22/-2

x= 11

so no.s are -x= -11

and -x-1 = -12
