Answer: -5<x<10
Step-by-step explanation:
1) Look at the problem and think about how to solve it.
2) The -1 can be added to the -6 and 9 because what you do to one side you have to do it to the other.
3) You would want to move the -1 to both sides but have to get rid of the -
4) -6+1 is -5 and 9+1 is 10
5) therefore -5<x<10 is the answer
