Answer:
The question is wrong, c will come instead of 5
The given linear equation is 2x + cy = 8.
By the given condition, x and y-coordinate of given linear equation are same. i.e x = y
Put y = x in the equation. we get,
2x + cx = 8
⇒
cx = 8 - 2x
c = 8/x-2x/x
Hence, the required value of c is 8/x-2x/x
