For this case we have the following system of equations:

We solve by the matching method.
Matching we have:

Thus, the solution of the system is given by:

Answer:

Answer:
Step-by-step explanation:
p = (3n + a)/(n + a)
Cross multiply
p(n + a) = 3n +a
pn + pa = 3n + a
pa - a = 3n - pn
a(p - 1) = n(3 - p)
Dividing by p - 1
a = n(3 - p)/(p - 1)
Answer: The graph is shown below
The solution to the system is (x,y) = (2,3)
=============================================================
Explanation:
To graph
, we need two points. Generating any (x,y) point involves picking a random x value to find its paired y value. For instance, if you plugged in x = 0, you should get to y = -2 which is the y intercept. Then trying something like x = 2 will lead to y = 3. This line goes through (0,-2) and (2,3). This line is shown in red below.
The blue line is horizontal and goes through 3 on the y axis. Every point on this horizontal line has the same y coordinate of 3. The x value doesn't matter, so it's not part of the equation y = 3.
The intersection of the red and blue line is the solution to the system. That intersection occurs at (x,y) = (2,3). This means x = 2 and y = 3 pair up together to make both original equations true.
Since this system has at least one solution, we consider it a consistent system.
