Answer:
y = -3
Step-by-step explanation:
Add 2 to each side to isolate the -3y. Doing this leaves you with -3y=9. You then divide each side leaving you with y = -3
The ratio is 1/2in to 5ft, or 1in to 10ft. That means for every 1 inch there will be 10ft. Since the room in the drawing is 2 inches long, the actual length of the room will be 20 feet long.
