Question

Two numbers differ by 5. If their sum is 19, then
find the two numbers
Option A
14,5
Option B
12,7​

Answer 1

Answer:

option B

Step-by-step explanation:

let one number be x and ithe be y

5+x=19-x

x+x=19-5

2x=14

x=7

x+y=19

7+y=19

y=19-7

y=12

Answer 2

Answer:

Option B is correct.

Explanation:

Let two numbers be x and y respectively.

x-y=5 -----1

x+y=19 ------2

From 1 we get,

x=5+y -------3

From 2 we get,

x=19-y --------4

From 3 and 4 we get,

5+y=19-y

y+y=19-5

2y=14

y=14/2= 7

By substituting y=7 in eq3 we get,

x=5+7

x=12

Since x=12 and y=7

Therefore, Option B is correct.
