Answer: The two numbers are 39 and 41
==================================================
Work Shown:
x = some odd number
x+2 = next odd number
eg: x = 3 and x+2 = 3+2 = 5
Add up those two expressions, set the sum equal to 80, and solve for x
(x) + (x+2) = 80
2x+2 = 80
2(x+1) = 80
x+1 = 80/2
x+1 = 40
x = 40-1
x = 39
----------
Another way to solve is to do this
2x+2 = 80
2x = 80-2
2x = 78
x = 78/2
x = 39
-----------
Either way, the solution is x = 39 which means the next odd number up is x+2 = 39+2 = 41
To check the answer, add up the two values
39+41 = 80
This confirms we have the right answer.
