Without the specific system of equations that was provided in part A, I am unable to solve it. However, the most common methods to solve systems of equations are substitution, elimination, or graphing.
Once the system of equations is solved, the solution for part D would represent the values of the variables in the system that satisfy both equations simultaneously. This means that the solution is the point in the coordinate plane where the two lines represented by the equations intersect. In terms of the situation being described in part A, the solution would represent the values of the variables at which both conditions are met.
