Just like equations: We can solve this "inequations"
5 > r - 3
Adding 3 to each side, we have
5+3 > r-3+3
8 > r or r<8

5 > r - 3
add 3 to both sides:
8 > r
r < 8
So we know that r can be anything less than 8. This means that a, b, and d are all true. The only one that isn't true is "c" because r must always be less than 8 so it cannot equal 8.

The inequality symbol changes when you multiply or divide by a negative number. not transposing
5 > r - 3
5 + 3 > r - 3 + 3
8 > r

Add 3 from both sides:
8>r
The answer is d.

Are you an American student? I'm shaking if the answer is yes.
