How man possible solutions are there for these equations?

Question

x-3y=-3, -2x+6y=12

 

a)one solution

b)infinite number of solutions

c) no soloutuon

Answer 1

The two equations are:

                    x-3y=-3

                  2x+6y=12 which, after diving both sides by -2, is:   x - 3y= -6

 

These lines are parallel, so they have no solution (do not intersect).
