I need help solving this system of linear equations. ?

Question

The two equations are -9x - 3y = -7 and the other equation is

3x + y = -5 So is the answer 0 or what i got is no solution or is it undefined?

Answer 1

if you set each equation equal to y you get

1st equation  -3y = 9x -7

                      y = -3x +7/3

2nd equation   y = -3x -5

they are parallel lines so the answer 0 means no solutions
