Question

the sum of two numbers is 2 . if their difference is 20, find the numbers​

Answer 1

let take one of them at X and another as y

then x plus y equals to 2

and x minus y equals to 20

or, x equals to 2 - y

or, 2-2y=20

-2y = 18

and y= -9

x= 2-(-9) =11

Answer 2

Answer:

x = 11

y = -9

Step-by-step explanation:

Let two numbers be x and y.

x + y = 2

x - y = 20

2x = 22

x = 11

x + y = 2

11 + y = 2

y = 2 -11

y = -9
