I’m not sure how to do this and I’ve tried everything pls help

Answer:
No you didn't try everything.I think it's solvable
Step-by-step explanation:
a= -2, b= 3, c= 2, d= -3
So
[tex]c - b = 2 - 3 = - 1 \\ d - c = - 3 - 2 = - 5 \\ a - c = - 2 - 2 = - 4[/tex]
Hope this helps please mark me BRAINLIEST. Thanks
