Question

write down a pair of integers where ;
a. seem in -7

b. difference is -10 ​

Answer 1

Answer:

-8.5 and 1.5

Step-by-step explanation:

let first number be x and second be y.

we know that :

x+y= -7 ....expression 1

x-y=-10 .....expression2

adding the LHS and RHS of both the numbers accordingly.

x+y+x-y = (-7) + (-10)

2x = -17

x= -8.5

So, x+y = -7

-8.5 + y = -7

y= -7 + 8.5

y = 1.5
