Can someone PLEASE explain this problem to me. I’ve been working on it for over 3 hours now.

A) Rewrite the 2nd equation to get x = 2y -8
Replace x in the 1st equation with this.
3(2y-8) -6y = -8
Simplify:
6y -24 -6y = -8
Combine like terms :
-24 = -8
Since the 6y and -6y cancel each other out and -24 does not equal -8, there is no solution.
B) In order to have a solution, the two lines would need to cross each other. Since there is no solution, the two lines never cross each other.
