Hi,         
Solving sytem by elimination method
x-2y = -5
-3x-2y=-9

 -x+2y = 5    |Multiplying each term of the first equation by -1 to eliminate y
-3x-2y=-9
  -4x = -4
 {{{highlight (x = 1)}}}

{{{x-2y = -5}}}
   1 - 2y = -5
      -2y = -6
 {{{highlight(y = 3)}}}

CHECKING our Answer
-3x-2y = -9
-3 -6 = -9
