The cost of 2 kg apples and 1 kg of grapes on a day was found to be ₹ 320. The cost of 4 kg apples and 2 kg grapes was found to be ₹ 600. If cost of 1 kg of apples and 1 kg of grapes is ₹ x and ₹ y respectively, represent the given situation algebraically as a system of equations and check whether the system so obtained is consistent or not.
Solve for x and y : √2 x + √3 y = 5 and √3 x − √8 y = −√6
The value of 'p' for which the equations px + 3y = p – 3, 12x + py = p has infinitely many solutions is :
The value of 'k' for which the system of linear equations 6x + y = 3k and 36x + 6y = 3 have infinitely many solutions is :
The value of c for which the pair cx – y = 2 and 6x – 2y = 3 will have infinitely many Solutions is:
Which of the following is a condition for unique solution of a pair of linear equations?
