In how many ways could the traveler schedule all three tours in one day, with the museum tour being after noon?

Please explain it to me if u can.

Solve the system of equations by the addition method. If the system does not have a single ordered pair as a solution, state whether the system is inconsistent or dependent.
-6x + 5y = 3
18x - 15y = -9
