Hey can you check this problem and tell me if its right.
Sure! Let me see it.
-4 -3 -2 -1 0 1 2 3 4
x+11+8x<29 -8x -8 x+11<11 -11 -11 x<0
Oh ok thanks.
This is wrong. Let me show you how to do it.
Can you tell me what I did wrong ?
What you did wrong was instead of combining the x and the 8x you subtracted the 8x from both side. What you need to do is subtract 11 from both sides. After you divide both ides by 9 to get ¨X¨ by its self. Also the dot on the number line would be open not closed.
