Question

1)Which of the following pairs of linear equations has unique solution no solution or infinitely many solutions.
vi) x-2y=6
3x-6y=0

Answer 1

Answer:

no solution

Step-by-step explanation:

no solution as equation is invalid as, when we multiply 3 in the first eqn. we get 18 whereas in the 2nd eqn we get 0 for the same eqn.

Answer 2

Answer:

vi) x-y = 9

x-y= 3

Step-by-step explanation:

x -2y = 6

x-y = 6+2

x-y = 9

3x-6y = 0

3x-y = 0+6

3x-y = 6

x-y = 6-3

x-y = 3
