Answer:
Infinite number of solutions
Explanations:
The given system of equation is:
21x + 6y = 42........................(1)
7x + 2y = 14............................(2)
From equation (1)
3 (7x + 2y) = 42
7x + 2y = 14..........................(3)
Since the two equations (2) and (3) are exactly similar, the system of equations has infinite number of solutions
