The sum of two numbers is 90. their difference is 12. what are the numbers?

39 and 51

The way to figure this out is to divide 90 by two

45 now subtract six and add six to 45 to achieve a difference of 12

45 - 6 = 39

45 + 6 = 51

Using algebra, we can say that the first number is x, and the second number is y.

x+y=90

x-y=12

Adding these two equations gives us:

2x=102

x=51

Plugging this into the first equation,

51+y=90

y=39.

So, the two numbers are 51 and 39.
