2x + 3y = 5x - y
Complete the missing value in the solution to the equation.
( ,0)

0

Step-by-step explanation:

If you replace y with 0 (which you do since you are given y = 0 and you are trying to find x from the (_,0) point), you get . The only way for x to satisfy this is x = 0.

6000x = 135000; x ≈ 23.

We are required to have one fire extinguisher for every 6000 ft of space in the building; this means we need to find out how many 6000-ft spaces we have in 135000.

Solving this equation, we divide both sides by 6000:
6000x/6000 = 135000/6000 = 22.5 ≈ 23
