A. x+70<63
B. x-70<63
C. x+70≤63
D. x+70≤-63
E. x-70≤63

Explanation:

From the given condition, we can say that -133≤x≤-7
Now, we need to see which option will give you the same range by expanding every option.
Eliminate options A and B as we need ≤.
Check Option C.
x+70≤63
-63≤x+70≤63
Subtract 70 from every part, we get -133≤x≤-7
