Is $(-1,-2)$ a solution to the following system: \[ \begin{array}{l} x+3 y=-7 \\ 3 x-2 y=12 \end{array} \]

Step 1 ：Substitute the values of x and y from the point (-1,-2) into the equations.

Step 2 ：For the first equation, we get -1 + 3*(-2) = -7 which holds true.

Step 3 ：For the second equation, we get 3*(-1) - 2*(-2) = 1 which does not hold true.

Step 4 ：Since both equations do not hold true, the point (-1,-2) is not a solution to the system of equations.

Step 5 ：\(\boxed{\text{Final Answer: } (-1,-2) \text{ is not a solution to the system of equations.}}\)
