2x - y  =  - 5 -  -  -  - (1) \\ 3x + 2y =  - 4  -  -  -  - (2)\\  \\  \textsf{adding \:eq(1) $ \times $2 and \: eq(2) } \\  \textsf{we \: get : } \\  \rightarrow \: 7x =  - 14 \\  \rightarrow \: x =  \frac{ - 14}{7} \\  \rightarrow \: x = 2  \\  \\  \boxed{ \textsf{x = 2}} \\  \\  \textsf{putting \: the \: value \: of \: x \: in \: eq \: (1)} \\  \\ 2x - y =  - 5 \\  \rightarrow2  \: \times 2 - y =  - 5 \\  \rightarrow \: 4 - y =  - 5 \\  \rightarrow \:  - y =  - 5 - 4 \\  \rightarrow \:  - y =  - 9 \\  \rightarrow \: y = 9 \\  \\  \boxed{ \textsf{y = 9}}
