Step-by-step explanation:
if x=1/4 then y=1/4-1/4=0
if x=13/4 then y=13/4-1/4=12/4=3
if x=2 then y=2-1/4=8/4-1/4=7/4=1 3/4
Basically, this problem is saying that if you multiply x by 3, then you will get a number that is one less than y. So, if you switch that around a bit, then the problem is saying that if you subtract 3x from y, you'll get 1.
Your final answer should be y - 3x = 1.
The model is 1:50 so take 11/5 and multiply it by 50 and you get 110, so the window is 110 inches long
