Answer 1

Answer:

ʜᴇʀᴇ ɪs ʏᴏᴜʀ ᴀɴsᴡᴇʀ ⬇️

Step-by-step explanation:

ᴛʜᴇ sᴜᴍ ᴏғ ᴛᴡᴏ ɴᴜᴍʙᴇʀs ɪs 4 ᴀɴᴅ ᴛʜᴇɪʀ ᴅɪғғᴇʀᴇɴᴄᴇ ɪs ᴢᴇʀ0.

x + ʏ = 4

x - ʏ = 0

ᴀᴅᴅs ᴛʜᴇ ᴇǫᴜᴀᴛɪᴏɴs ᴛᴏɢᴇᴛʜᴇʀ 2x = 4 ➡️ x = 2 ᴛʜᴇɴ ʏ=2

2 + 2 = 4 ᴀɴᴅ 2 - 2 = 0

Answer 2

Answer:

-3, 7

Step-by-step explanation:

let the numbers be X and Y

so according to the given information,

X + Y = 4 -------------- a

X - Y = -10 --------------b

by adding a and b equations we get 2X = -6 i.e. X= -3

by substracting a and b equations we get 2Y = 14 i.e. Y= 7
