Answer:
The amount of water left is 1550 litres
I would say 95/6 because you multiply 5 and 15 and turn it into an improper fractions
<u>Given</u>:
The system of linear equations are
and 
We need to determine the solution to the system of equations using substitution method.
<u>Solution</u>:
The solution can be determined using the substitution method.
Let us substitute
in the equation 
Thus, we have;




Thus, the value of y is -17.
Substituting
in the equation
, we get;


Thus, the value of x is -13.
Hence, the solution to the system of equations is (-13,-17)
Since 1 kiloliter = 100 centiliter, so
7.7 kL (100 cL/1 kL) = 700 cL
Hope this helps.
