The sum of two numbers is 15. if one number is subtracted from the other, the result is -3. find the numbers

The numbers are 6 and 9

Step-by-step explanation:

Let the two numbers be x and y.

Given :

The sum of two numbers  equation:1

Also the difference of x and y   equation:2

On solving equation:2  

                                         equation:3

Putting this value of x in equation 1.

     Putting value of y in equation:3 to find x

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
