7. Solve the system of equations using the Substitution Method or the Addition Method. Write all solutions as ordered pairs if possible. If the system is inconsistent, write inconsistent. If the system is dependent, write dependent and give 3 individual solutions for the system. (15 pts) You must show all work details to receive credit. a) y=1/2x-2
2x-5y=10
b) 3(x-3)-2y=0
2(x-y)=-x-y
