Question 1150103: Solve the system by the method of your choice. Identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets.
6x - 3y = 5
-12x + 6y = -15 Answer by greenestamps(13200) (Show Source):
When the equations are given in this form, elimination is (for me) by far the easiest way to go.
6x - 3y = 5
-12x + 6y = -15
Double the first equation to get an equation with "12x"; then adding the two equations will eliminate x:
12x - 6y = 10
-12x + 6y = -15
---------------
0 = -5
That equation is FALSE; that means the system has 0 solutions.
