Question

Find the value of c for which the equation cx-y=2 and 6x -2y =4 will have infinitely many solutions.

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

c=3

Step-by-step explanation:

for infinitely many solutions, a1/a2=b1/b2=c1/c2

cx-y=2                     --------(1)

6x-2y=4

2(3x-y)=4

3x-y=2                      --------(2)

comparing (1) and (2)

cx/3x=-y/-y=2/2

c/3=1=1

c/3=1

c=3
