We need to check whether the system of equations is consistent or inconsistent.
As we know the formula for checking the consistency :
In first equation we have
similarly,
In the second equation we have
So, According to question, we have

Answer:
205 litres
Step-by-step explanation:
Given:
Volume of water is given as:
(in litres)
<em>m</em> is the time in minutes spent filling water in Eduardo's pool.
To find:
Volume of water in the pool after the water is filled for minutes.
Solution:
Here, volume of water in the Pool (in litres) is given by the equation:
....... (1)
Where m is the time for which Eduardo fills the pool.
Here, we are also given that
m = minutes =
minutes
And we have to find the value of V after minutes.
Let us put the value of m as minutes in the equation (1) to find the value of V.
So, the volume of water in the pool after minutes is <em>205 litres.</em>
