Question

The linear equation 2x + cy = 8 has equal values of x and y for its solution when c is equal to​

Answer 1

Step-by-step explanation:

Take x=y=1

Therefore 2+c=8

C=6

Similarly we take x=y=2

We get c=2

Answer 2

Answer:

c=2

Step-by-step explanation:

2x - cy = 8 and x =y

so, 2x - cx = 8

x (2 - c) = 8

x = 8 / (2-c)

denominator should not be zero

so, 2 - c = 0

c = 2
