Answer: The first equation should be multiplied by 9 and the second equation by −4, to eliminate the y-terms and solve for x in the fewest steps.
Step-by-step explanation:
Given : Equation (1) 5x − 4y = 28
Equation (2) 3x - 9y = 30
to eliminate the y-terms and solve for x in the fewest steps, we should multiply equation (1) by 9 and equation (2) by -4 such that
9(5x − 4y) =9 (28)⇒45x-36y=252
-4(3x - 9y) = -4(30)⇒ -12x+36y= -120
Now adding both equations, y-term eliminated and we get, 45x-12x=132
⇒33x=132⇒x=4.

Based on the information, it is expected Fareed can be assigned to live on any of the floors.
<h3>What condition limits Fareed's assignment?</h3>
The only condition that limits the floor Fareed can be assigned to is that he cannot be immediately below Damaris. This means that as long as Damaris is not immediately above him, he can be assigned to all floors. Here are two possible arrangements:
- Eugenio (5th floor)
- Damaris
- Cindy
- Fareed
- Guzal (1st floor)
- Guzal (5th floor)
- Eugenio
- Damaris
- Cindy
- Fareed (1st floor)
