To find the solution of the system, we can substitute the value of y from the first equation into the second equation.
From the first equation, we have y = -3x.
Substituting y = -3x into the second equation, we get 3x + 2(-3x) = 6.
Simplifying, we get 3x - 6x = 6.
Combining like terms, we get -3x = 6.
Dividing both sides by -3, we get x = -2.
Substituting x = -2 into y = -3x, we get y = -3(-2) = 6.
Therefore, the solution of the system is (-2, 6).
The correct answer is C. (-2, 6).
