Question

find ot the value of c for which the pair of equations cx -y =2 and 6x -2y = 4 will have infinitely many solutions​

Answer 1

Step-by-step explanation:

cx - y = 2

6x - 2y =4

cx - y - 2 =0

6x - 2y - 4 =0

c - 1 - 2

__=____=____

6 - 2 - 4

c 1 1

__=_____=_____

6 2 2

c 1

__=___

6 2

2c = 6

c = 6 /2

c = 3
