Answer:
x=-3, y=3
Step-by-step explanation:
what we do is we multiply the second eq by 3.
so it becomes:
-3x+9y=36.
now we add the 1st equation from before and this new 1.
so adding 3x + y = -6 and -3x+9y=36 becomes:
(x cancels out): 10y = 30, y = 3. now that we have y, we subsitute y into a equation with x; lets take the first eq. so it becoems 3x + 3 = -6
which becomes 3x=-9
which becomes x=-3
so now you hvae x= -3, and y = 3.
