check whether (1/2,-5)is the solution of the equation 2x-y=6 or not ​

1 thought on “check whether (1/2,-5)is the solution of the equation 2x-y=6 or not ​”

1. Step-by-step explanation:

   2x−y=6

   2x=6+y

   (A) (3,0)

   LHS=2x−y

   =2(3)−06=6RHS

   (3,0) is a solution

   (B) (0.6)

   LHS=2xy⇒2(0)−6⇒−6

   

   =RHS

   (o,6) is not a solution

   (C) (2,−2)

   LHS2(2)−(−2)⇒6⇒RHS

   (2,−2) is asolution

   (D) (
