You can
put this solution on YOUR website!No point feeling like an idiot :-)
Treat both parts separately, and solve them:
-18 < 6x-7
-11 < 6x
6x > -11
x > -11/6
this is one answer. Now for the other:
6x - 7 <= 17
6x <= 24
x <= 3
so the answer that satisfies both parts is that:
-11/6 < x <= 3
ie any number between -11/6 and 3 satisfies both parts - so draw a number line of this.
Hope this helps? :-)
