x+10>10 and x+10<9

+5

x+10>10   subtract 10 from both sides

x > 0

 

x+10<9   subtract 10 from both sides

x < -1

 

If, by the word "and," you want the intersection of these two solutions......it doesn't exist.....there is no "overlap" on the number line of the two solutions......the answer is { }  = the empty set
