Question

x = 2, y = -1 is a solution of the linear equation a) 2x + y = 0 b) x + 2y = 0 c) x + 2y = 4 d) 2x + y = 5​

Answer 1

Step-by-step explanation:

x = 2 and y = -1 We will check by substituting the values in the given equations (a) 2 - 2 = 0 which is true Thus, x + 2y = 0 is the equation Read more on Sarthaks.com - https://www.sarthaks.com/1072062/x-2-y-1-is-a-solution-of-the-linear-equation-a-x-2y-0-b-x-2y-4-c-2x-y-0-d-2x-y-5

Answer 2

Answer: b) X+2Y = 0

Step-by-step explanation:

Putting the values of X and Y in the equations to varify L.H.S=R.HS

b) X+2Y = 0

Putting the values of X and Y on the left hand side .

=>L.H.S

=>X+2Y

=> 2+2(-1)

=> 2-2= 0 = R.H.S
