Answer 2

please note that if I multiply both sides of your first equation by -2, I get:
\[-6x+18y=-6\]
whereas your second equation is:
\[6x-3y=-24\]
Now, please add those equations side by side, what do you get?

Answer 3

21y=-31?

Answer 4

did the X canceled out?

Answer 5

18y-3y=-6-24
or:
15y=-30
what is y?

Answer 6

y=15?
