Systems of equations are bundles of equations that all relate to a common problem. for instance, combine two equations that each give the distance (y) that two different cars drive in a given amount of systems of equations are bundles of equations that all relate to a common problem. for instance, combine two equations that each give the distance (y) that two different cars drive in a given amount of time(x) to form a system of equations:

y = 60x + 5
y = 40x + 40

one value of x will yield the same value of y in each equation. what does this solution represent in this situation? can you think of any other scenarios where two linked equations could provide a useful answer? how do systems of equations make problems easier to comprehend?
