No unique solution, equations are the same
+3 +1 -11
-9 -3 +33

1 0 -3.667
0 0 0
x = -3.6666.... or -11/3
y can be anything
equation 2 is -3 times equation 1
Therefore the two lines are the same, they do not intersect, there is no solution
Write the system of equations as an augmented matrix. Then solve for x and y.
3x+y=-11
-9x-3y=33
