Question 153405: Solve the equation |y-6|+2y=9
So far, I have:
y-6=-(9-2y)
y-6=-9+2y
-y=-3
y=3
I tested that, and it is correct. Am I on the right track, and/or is there another answer? How do I find this additional answer?
Also - Graph the equation y=|x+4| + |3-x|
I know how to graph, but I am not quite sure how to start off. Many thanks if you can simplify it.
