Just substitute in the number 3 for x then subtract 3 at both sides and youll have y=7
X + 12 = n
N is 5 more than twelve so add 5 to 12 and you get 17.
For this case we have the following inequality:

The first thing we must do is to graph the linear function:

Then, we must evaluate ordered pairs in the following way:
(x, y)
The ordered pairs that meet the inequality, will be included as part of the graph.
Therefore, the shaded region contains all the ordered pairs that meet the inequality.
Answer: See attached image.
