the answer is s=4
first step is to solve for d
d+s>-3
subtract s from both sides
d+s-s>-3-s
d>-3-s
now we have two inequalities:
d>-3-s and d>-7
since the left sides (d) are equal the right sides must be equal as well
now solve for s
-7=-3-s
s=-3-7
s=4
hope this helps! also hope this was the right question haha
