SOLUTION: graph: -6<2x<12

Question 289675: graph: -6<2x<12
Answer by j1mmy94(14) (Show Source): You can put this solution on YOUR website!
The first thing you want to do is divide 2 on all sides because you want x by itself. Then you should get:
<-----------------o============o--------->
.............................-3.......................6
Note: Ignore the periods, because i typed it to make the numbers match the o's.
When the symbol is < or >, this means that the numerical answer in the inequality is not a solution for the variable. Thus, we graph it as an open circle. DO NOT make a dot and shade it in!
We can plus in integers for x to find where the solutions are on the line graph.
I used -2 and 5 for x.
Using -2: becomes This is true because -2 is greater than -3 and less than 6.
Using 5: becomes This is true because 5 is greater than -1 and less than 6.
We can tell that the solutions are between -3 and 6. I hope this helps! :]
This is the graph:
<-----------------o============o--------->
.............................-3.......................6
