"Opposites" cannot mean additive opposites since, by definition, their sum must be 0.
So "opposites" is likely to mean multiplicative opposites.
This gives the equation x + 1/x = 100
Then
the two numbers are 0.010010 and 99.989999 to 6 dp.
Yes opposite numbers add up to 7

99 and -99
change the sign and do the opposite operation.
36 and 64
0 and 100.

On a six-sided cube die, the opposite side is the 2. (the opposite sides add to 7)
5050
two numbers that add up to zero. for example -13, and 13.

If you've written that correctly, there aren't two whole numbers that satisfy those conditions. -20 and -5 add to -25, but multiply to 100. -25 and 4 multiply to -100, but add to -21.
