Absolute value Quest, urgent
a) |x-2| + |6-3x| = 12x
I have a question about y this negetive becomes a positive.. ::
Steps ::
|x-2| + -3|x-2|
|x-2| +3 |x-2| = 12x > this step if i factored out.. |x-2|+[-3]|x-2| , shouldn't it be -3 +1 =2?? why does it become 4
4|x-2| = 12/4
|x-2| = 3x
If i factor out a -3, then add the "1" on the left side it should be -2 no? in my notes its written this way and is correct in the book, why did that -3 become positive?
