Question

is y=2x and x+y=0 infinite or no solution?

Answer 1

i have no solution

Answer 2

@krissywatts I have a solution.---> (0,0) Substitute in both the equations and it satisfies both. Hence solution of the system of equations exist

Answer 3

if you substitute first with second equation or viceversa you get 0 so its no solution cause in both ways you get 0/3 =0

Answer 4

@Kryten , both the lines intersect at (0,0) and hence they have a solution
