Question

13. Find two numbers whose sum is -12 and difference is -2.

I need step by step explanation​

Answer 1

Step-by-step explanation:

let first number be x

and second be y

x+y = -12

x-y = -2

solving this linear equation we'll get=>

2x = -14

x = -7

x+y = -12

y = -12+7

y = -5

First number = x= -7

second number = y = -5

Hope it helps uh!
