Question

___+___= 8
___--___=6
13. 6​

Answer 1

Answer:-

First let us try to solve the two left boxes top and down.

We need two numbers which sum to a total of 13

Let us assume the two numbers to be 7/2 and 19/2

7/2 +19/2 = 13

Next , the second box which which sum to a total of 13.

Let us assume the two numbers to be 9/2 and 7/2

9/2 +7/2 =8

Now,

To solve horizontally,

7/2 - 8 = 9/2

and,

19/2 -6 = 7/2

So, the order would be,

7/2   +       9/ 2   =  8

+               +

19/2    -      7/2    =  6

=                =

13                8

Answer 2

Answer:

1+7=8

1-7=6

Explanation:

Let the numbers be x and y,such that

x+ y =8. and x-y =6

=> x+y=8............(a)

=> x-y=6.............(b)

x+y=8. => x=8-y........(c)

put =n(c) in =n(b)

=> 8-y-y=6 =>8-2y=6

=> 2y= 6+8. => y= 14/2

=> y= 7...........(d)

Now,put equation (d) in equation (c),we get

x= 8-y => x= 8-7= 1

Therefore the two numbers are 1 and 7.
