Question

The sun of two numbers is 60 and their difference is 40. find the number. ​

Answer 1

Answer:

X+Y=60 X-Y=40 after adding both the equation we will get 2X=100 then,X=50 and Y=10

Answer 2

Answer:

the numbers are 50 and 10

Step-by-step explanation:

let the numbers be x and y

sum of two numbers = 60

x + y =60

=> x = 60 - y

difference of two numbers = 40

x - y = 40

(60 - y) - y = 40

60 - 2y = 40

60 - 40 = 2y

20 = 2y

y = 20/2

→ y = 10

→ x = 60 - 10 = 50
