On the home work it showed that this is the correct process can you please explain why it is different from what I see on your panel.
x=6
9 > 2 (6) - 4
9 > 8
Answer provided by our tutors
After solving the equation:
9=2x-4
you get
x = 6.5
Now, you want to graph the solution, and you want to see if "6" belongs to the solution.
You do this by plugging the value "x = 6" into "9>2x-4" and you get:
9 > 2*6 - 8
9 > 8 and this is correct, so "6" belong to the solution interval (-~, 6.5)
