-2a + 3b = 9 / x 2;
-4a + 6b = 18;
Then, -4a + 6b = 18
+4a - 2b = 3
__________________(+)
We obtain 4b = 21;
b = 21/4;
-2a + 63/4 = 9;
-8a + 63 = 36;
-8a = - 27;
a = 27/8 ;

How to graph the linear equation?</h3>
Here we have a linear equation:
y = -x
To graph it, we just need to find two points and the line, and then connect the points with a line.
Evaluating in x = 0, we get:
y = -0 = 0
Then we have the point (0, 0).
Evaluating in x = 1 we get:
y = -1
So we have the point (1, -1)
Now we just need to graph these two points and connect them with a line, the graph can be seen below.

Answer:
C
Step-by-step explanation:
The answer simply has no solution. A solution of a system of equations is determined by how many times they intersect (with lines it will only ever have one or zero solution) and unless the angle is unnecessarily small in this question, its safe to say those line, no matter how far you go, will never have a solution.
