Answer:
x = 3 3/8
Explanation:
I believe you would have to solve it with the reverse operation. If
x - (-2 7/8) = -1/2, than x has to be -1/2 more than -2 7/8. Because they are both negative numbers, the answer will be positive.
-2 7/8 + -1/2 = 3 3/8 x = 3 3/8
3 3/8 - (-2 7/8) = -1/2
Feel free to correct me. I hope you do well.
