Question

write write a pair of negative integer whose sum is -10 and difference is 4​

Answer 1

Step-by-step explanation:

let the number be -x and -y

case 1

-x -y = -10

case 2

-x+y = 4

adding case 1 and case 2

we get -2x = -6

x = 3

and y = -10 +3/-1

y = -7 /-1

y = 7

change the sign of value of x and y

therefore

two negative numbers are

-3 and -7

hope u understand ...

mark me as brainliest and for more follow me .. and also I solve physics .. so yeaa for doubt u can follow me

Answer 2

Answer:

let the 2 no.s be x and y

A/q,

their sum=-10

=> x+y=-10-----(i/)

their difference=4

=>x-y=4

on adding both the equations

x+y=-10

x-y=4

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

2x=-6

x=-3

on substituting value of x in equation ii

x-y=4

=>y=4-(-3)

=7
