Use Cramer S Rule to Find the Solution Set for the System

Short Answer

Use Cramer s rule to find the solution set for the system. $$\left( \begin{array} { c c c c } 3 x - 3 y & = & - 12 \\- x + 2 y & = & 9\end{array} \right)$$ If the equations of the system are dependent, or if a system is inconsistent, so indicate. In those cases enter dependent or inconsistent . Otherwise, enter your answer in the form ( x , y ).
