To find two numbers that add up to 28, we can set up an equation as follows: x + y = 28. There are multiple pairs of numbers that satisfy this equation, such as 14 and 14, 15 and 13, 10 and 18, etc. These pairs can be found by trial and error or by algebraic methods such as substitution or elimination.

161
The numbers are 6 and 28
-175

-28
18 and 10 18 x 10 = 180 18 + 10 = 28
28 x 10

-5
The numbers are: (-14 + the square root 132) and (-14 - the square root of 132)
-28
Ignoring the order of the primes, there is only one way.
