Answer:
y=9
Step-by-step explanation:
-2y + 6 = -12
-2y - 6 = -6
-2y = -18
-2/y= -18/-2
y= 9
You need to subtract six one both sides first, that will cancel out the positive six, and that will also give you this:
-2y = -18
Now, divide negative two on both sides, that will cancel out both the negative signs, and it will also cancel out the two and it will give you your final answer:
y = 9
