Answer:
[tex]\boxed{\sf{r < -1}}[/tex]
Step-by-step explanation:
Isolate the term of r from one side of the equation.
-5+5r<-10
First, add by 5 from both sides.
-5+5r+5<-10+5
Solve.
-10+5=-5
Rewrite the problem down.
5r<-5
Then, you divide by 5 from both sides.
5r/5<-5/5
Solve.
Divide the numbers goes from left to right.
-5/5=-1
r<-1
Therefore, the final answer is r<-1.
