The solution is C. Let’s start by identifying the equations without inequalities. Since there's a dotted line at y = 1, options A and B can be disregarded. Dotted lines indicate exclusivity, so they do not encompass the = sign. Therefore, the answer must be C.
Response:
.
Detailed explanation:
We have a set of equations provided. Our task is to find the solution for this system.


Starting from equation (2), we will derive:

Next, by inserting this value into equation (1), we will achieve:

After multiplying both sides by 3, we will arrive at:








Now substituting this back into equation (2), we will find:



Thus, the solution to our specified set of equations is
