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
Multiply 1st equation byy - 3 getting:
18x -15y =-9
This is the same as the 2nd equation , so they are the same line and there is an infinite number of solutions.
It is a consistent, dependent system.

-6x + 5y = 3
18x - 15y = -9
Multiply 1st equation by 3
-18x + 15y = 9
18x - 15y = -9
---------------------------
0 = 0
This is a indeterminated system and has infinite solutions.
In the 1st equation:
-6x + 5y = 3
5y = 3 + 6x
y = (3 + 6x) / 5
There is infinite solutions:
Each real value of X gives a value of Y.
The solution is on a straight line. y = (3+6x)/5
