hey,
how did you get x is more than or equal to 4? Shouldn't it be x is less than or equal to 4? Here's my reasoning.
1. Distribute the x
2.Add 12 to both sides
3. subtract 4 from both sides
4.subtract 5x from both sides
5. divide by negative 11 (you flip the sign when you divide by a negative)
6. You wind up getting x is less than or equal to negative 4.
start with:
I presume you mean distribute the 61. Distribute the x
2.Add 12 to both sides
3. subtract 4 from both sides
4.subtract 5x from both sides
5. divide by negative 11 (you flip the sign when you divide by a negative)
Yes, but that is what earboth has:6. You wind up getting x is less than or equal to negative 4.
and are the same thing.

Hello,
sorry for this late reply:
1. if you read my answer from right to left you'll get exactly your answer
2. I collected the x at the RHS to avoid the division by a negative number. As you have pointed out you have to change the -sign into a -sign, which I don't have to do.
