Answer

$Final Answer: (- 1, - 2) is not a solution to the system of equations.$

Steps

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 ： $Final Answer: (- 1, - 2) is not a solution to the system of equations.$
