Step-by-step explanation:
[tex]6x+2y=-2[/tex]
[tex]3x-2y=-5[/tex]
Add both equations. combine like terms
6x +3x becomes 9x
+2y -2y becomes 0
-2 and -5 becomes -7
so when we add both equations we get
[tex]9x+0y=-7[/tex]
ignore 0y
[tex]9x=-7[/tex]
By adding two equations we get 9x=-7
answer : [tex]9x=-7[/tex]
