-3x-2y=-12
9x+6y=-9
\(\text{Determinante }~D=\begin{vmatrix} -3 && -2 \\ 9 && 6 \end{vmatrix} =(-3)\cdot 6 - 9\cdot (-2)= -18+18 = 0\\ D = 0 \qquad \Rightarrow \qquad \text{ no solution }\)
-3x-2y=-12 divide everything by 2 → ( -3/2 )x - y = -69x+6y=-9 divide everything by 6 → (3/2)x + y = -3/2
Add these equations together
0 + 0 = -6 - 3/2
0 = - 15/2
This is never true.....so.....this system has no solution, Paypay
