Question

for what value of k, x = 2 and Y = - 1 is a solution of X + 3 Y - k= 0​

Answer 1

Step-by-step explanation:

Hi,

Given : X = 2 and Y = -1

Given equation is X + 3Y - K = 0

Putting the value of X and Y in ,

X + 3Y - K = 0

2 + 3 × -1 - K = 0

2 - 3 - K = 0

-1 - K = 0

-K = 1

K = -1.

Hope it will help you :)

Answer 2

Step-by-step explanation:

x + 3Y - K = 0

we have given that X = 2 , Y = -1

substitute the value of X and Y in the given equation

2 + 3(-1) - K = 0

2 - 3 - K = 0

-1 - K = 0

K =. -1

hope you understand.....
