Question

The sum of two integers is 8. their difference is 6. what are the two integers?

Answer 1

Let the integers be x and y

i.e x + y = 8 ........................ I

x - y = 6 ...........................ii

solving simultaneously

Add equation i and ii

⇒ 2x = 14

x = 7

substitute x = 7 into equation i

7 + y = 8

y = 1

therefore the integers are:

7 and 1

Explanation:

Answer 2

The numbers are 7,1

Explanation:

Let the one number be x

Then other number = 8 - x

x - (8-x) = 6

x - 8 + x =6

2x = 6 +8

2x = 14

x = 14/2

x = 7

So the other number =1
