I have the inequality:
I have to find all the possible integer values of x in the inequality above.
First I multiplied both sides by 5 to get:
I then divided the first sub-inequality (SI 1) by 2:
I then divided the second sub-inequality (SI 2) by 2:
Through combining SI 1 and SI 2 I form the following:
Here comes the easiest part of all, but somehow the hardest at the moment for me. I now have to find all the possible integer values of x. I easily understand that -5 will NOT be included as a possible integer because of the sign next to it. However the 7.5 part with the sign confuses me.
Is 8 included or not? WHY?
Or do I just have the possible integers to be:
-4,-3,-2,-1,0,1,2,3,4,5,6 and 7 ?
Whether 8 gets included or not, please explain to me why.
Thanks a lot.
