Answer:
(10 + x) liters represents the total number of liters in the mixture
Step-by-step explanation:
Here, we want to find and expression representing the total number of liters in the solution; we proceed as follows;
The simple answer here is the sum of the liters of both solutions.
Mathematically, that would be 10 + x liters
We should understand that we do not have anything to do with the concentration of either solution and thus, the total amount in liters of both will be 10 + x liters
