JC HL Question
-17<1-3x<13 final answer -4 and 6
my workings
- 1-3 = -2
-17 + 13 = -4
- -2-4 = 6
Final answers -4 and 6?
Just wondering or should I learn the example from study clix?

3x < 1 + 17
3x < 18
x < 6
1 - 3x < 13
1 - 13 < 3x
-12 < 3x
-4 < x
This is how it should be laid out but as long as you got the same answers, you should for certain get marks.
