Answer:
Subtract ax from both sides. ax + by − ax = c − ax.
Simplify. by = c − ax.
Divide both sides by b ; b ≠ 0. by b = c b − ax b ; b ≠ 0.
Simplify. y = c − ax b ; b ≠ 0.
she drinks 9/2 ounces of water in 1 hour
Step-by-step explanation:
On average, the person drinks 1/2 of a 6-ounce glass of water in 2/3 hour.
First of all, we have to rewrite the amount of water in a single fraction: we have
This means that the person drinks 3 ounces of water every 2/3 hours.
In order to find how much water she drinks in one hour, we use the following proportion:
where
x is the amount of water she drinks in one hour.
Solving the equation for x,
Therefore, she drinks 9/2 ounces of water in 1 hour.

Let x be the number. If I understand the wording of the problem correctly, then the equation is this: x + (1/6)x + (5/2)x + 7 = 5/2 .
x = - 27/22 or - 1 5/22 if a mixed number is desired.
