Answer: the system of equations that represents this situation are
12x + 6y = 180
x = 2y
Step-by-step explanation:
Let x represent the number of hardcover books that were sold in a day.
Let y represent the number of paperback books that were sold in a day.
The discount bookstore sells hardcover books for $12 and paperback books for $6. The total sales that day were $180. It means that
12x + 6y = 180
The number of hardcover books sold that day was twice the number of paperback books. It means that
x = 2y
Answer:
the value of
such that there is no solution to the equation is
.
Step-by-step explanation:
Let first simplify the expression presented on statement. The equation has no solution if and only if
is eliminated in the process and an absurd is the result (i.e.
).






To obtain an absurd, we need that
. Hence, the value of
such that there is no solution to the equation is:

Let prove the certainty of the result. We find that an absurd exist: (
)
