Which system of equations has one solution?

Answer:
A is correct, when two lines have 1 intersection (1 solution).
Step-by-step explanation:
B Two lines are parallel => No intersection (no solution).
C Two lines are coincident => Many intersection (many solutions).
Hope this helps!
:)
Step-by-step explanation:
As these two lines are not parallel so going to intersect at one point so having one solution
