Question

If x = 2 and y = 1 one of the solutions of 4x + ky = 11 , then k =

Answer 1

Answer:

k=-7

Step-by-step explanation:

Given: x= 2 and y= 1

To find: The value of 'k'

Sol:

$4x + ky = 1 \\ 4 \times 2 + k \times 1 = 1 \\ 8 + k = 1 \\ k = 1 - 8 \\ k = - 7$

Answer 2

Answer:

k=-7

Step-by-step explanation:

Given: x= 2 and y= 1

To find: The value of 'k'

Sol:

\begin{gathered}4x + ky = 1 \\ 4 \times 2 + k \times 1 = 1 \\ 8 + k = 1 \\ k = 1 - 8 \\ k = - 7\end{gathered}

4x+ky=1

4×2+k×1=1

8+k=1

k=1−8

k=−7
