The required proportional amount of water is 15 gallons. Option B is correct.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
Let the amount of water be x and the amount of bleach be y,
According to the question,

y =kx,
And we have given k = 1/3
y = x/3

Now, put y = 5,
5 = x/3
x = 5×3
x = 15 gallons

Thus, the required proportional amount of water is 15 gallons. Option B is correct.

Step-by-step explanation:

Using a system of elimination is easy:

Bring the two equations up.

[tex]-6x + 9y = -12\\8x - 9y = -8\\[/tex]

Since we have 9y and -9y, they cancel each other out.

We now have:

[tex]-6x = -12\\8x = -8\\[/tex]

Now solve for x.

1. x = 2

2. x = -1.
