Question

The difference of two number is 2. Their sum is 12. Find the numbers

Answer 1

the numbers are 7 and 5

7 + 5 = 12

7 - 5 = 2

hope this helps !!

Answer 2

Let the two numbers be larger x and smaller y

The sum of two numbers is 12

x + y = 12

Their difference is 2

x - y = 2

x = 2 + y

Now substituting value of x from


x + y = 12

2 + y + y = 12

2 + 2y = 12

2y = 12 - 2

2y = 10

y = 10/2

y = 5

Substituting the value of y to derive value of x

x = 2 + y

x = 2 + 5

y = 7

The two numbers are larger 7 and smaller 5
