Question

Suppose that S and T are points on the number line.

If ST = 8 and S lies at 4, where could I be located?
If there are several locations, separate them with commas.

Answer 1

13, -4

Explanation:

If S is at 4, then for ST to = 8, you would add 8 to S, which you would get 13. You can also subtract 8 from S, which you would get -4.
