You want to keep the variable on the left and number on right.

So, we need to get rid of 9 and -4y. Let's start with 9.

4y+9=-4y-7

Subtract nine from both sides.

4y=-4y-16

Now add 4y on both sides.

8y=-16

Finally, divide both sides by 8 to get y=-?.

8y/8=-16/8

Therefore, the answer is y=-2.
