Is 8 a solution of x < -1 or x > 7? 
Please explain this to me as I literally don't know how to solve it.

zepdrix · Answer

It might make more sense to you if they had worded it like this:
Is `x=8` a solution of x < -1 or x > 7 ?

 Plug 8 in for x and see if both inequalities hold true.

zepdrix · Answer

Woops, we have an `or`,
so I guess you want to see if `either` holds true.

So 8 > 7 holds true right? @zepdrix

anonymous · Answer

yes, indeed 8 > 7, your kindergarden teacher was right
