Question

the sum of two numbers is 18 and their difference is 2 what are the two numbers

Answer 1

Answer:

let x be bigger and y be smaller no.

so,x+y=18

x-y= 2

Then,

add equation 1 and 2

you will get x=10 and y=8.

Hope this will right and help you..

Thank you.

Answer 2

Answer:

the two numbers are 10 and 8

Step-by-Step Explanation:

Let x and y be the two numbers.

It is given that their sum is 18 i.e,

i) x + y = 18

It is also said that their difference is 2 i.e

ii) x - y = 2

→ from i) we can get corresponding values of x and y i.e

x + y = 18

x = (18-y) — 1

x + y = 18

y = (18-x) — 2

→ rewriting, i) with 1 , we get,

x - y = 2

(18-y) - y = 2 (rewriting 1 here)

18 - y - y = 2

-2y = 2 -18

-2y = -16

y = (-16) ÷ (-2)

y = 8

x - y = 2

x - 8 = 2

x = 2 + 8

x = 10

therefore, the two required numbers are

10 and 8
