Question

sum of two number is 25 and their difference is 3 find the number

Answer 1

Answer:

Step-by-step explanation:

let the two numbers be x and y

according to question ,

x + y = 25 ----- eq 1

x - y = 3 -----eq 2

taking eq1,

x + y = 25

x = 25 - y

substituting the value of x in eq2,

x - y = 3

(25-y) - y = 3

25- 2y = 3

-2y = 3 - 25

y = -22/-2

y = 11

since x + y = 25

         x + 11 = 25

therefore x = 14

Answer 2

Answer: 14 and 11

Step-by-step explanation:

Let the one number be x .

And, other number be y .

▶Now, A/Q

→ Sum of two number is 25 .

°•° x + y = 25 ........... (1) .

And,

→ Difference of two number is 3 .

°•° x - y = 3 .......... (2) .

▶ Substracting in equation (1) and (2), we get

x + y = 25 .

x - y = 3 .

- + -

_________

=> 2y = 22 .

=> y = 22/2 .

•°• y = 11 .

▶On putting the value of y in equation (1) , we get

°•° x + y = 25 .

=> x + 11 = 25 .

=> x = 25 - 11 .

•°• x = 14 .

✔✔ Hence, the numbers are 14 and 11 ✅✅ .
