Step-by-step explanation:
The answer is always. Family.
The two equations represent the different speeds (60 and 40) that two cars are traveling and the distances where they began (5 and 40). The solution represents the time(x) when they have traveled the same distance. Graphically it is the point where they intersect.
Other scenarios would be any time you are comparing two things like cost to drive two different cars or internet services.
Systems of equations help us see each situation, in this problem the time and distance a car travels then relate it to another car's distance traveled at the same times.
