Answer:
Answer A- "The system of equations has one solution." :)
Step-by-step explanation:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. ... If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

t = amount of hours it takes to fill the tank.
let's say it takes "t" hours to do the whole tank, and we know the inlet pipe can do the whole tank in 10 hours, so, how much has it done in 1 hour only? well, since it takes 10 hours to do the whole tank, in 1 hour the inlet pipe has only done 1/10 of the whole job.
likewise, the outlet pipe can empty the whole thing in 14 hours, so how much has it emptied in 1 hour alone? well 1/14 of the whole tank.
keeping in mind both have done in 1 hour, only 1/t of the whole thing.
You can easily count the number of units is on the longer side which is 9 units
