Answer:

x = -10 and y = -8

you can multiply either the top or bottom equation by -1 so lets say you apply it to the bottom equation it’ll look like this:

-9x + 9y = 18

6x – 9y = 12

then the +9y and -9y will cancel out

-9x = 18

6x =12

then you add the two equations together

-3x = 30

divide both sides by -3

x = -10
