Step-by-step explanation:
Consider the given equation,
2x−ky+7=8 and x=2,y=1
Now, put these value of x and y in given equation,
2×2−k×1=8
4−k=8
k=4−8
k=−4
Hence, this is the answer.

x = 2 y = -1
1st Equation : 2x + ky = 1
Put the value of x and y
2 (2) + k(-1) = 1
4 - k = 1
4 - 1 = k
3 = k
[tex]\huge {\underline {\boxed{{\underline {\overline {\mid {\mid {\mathscr {\pink { k = 3 }
{\mid}}}}}}}}}} [/tex]
2nd Equation : x -2y = 4
x = 2 y= -1
2 - 2(-1) = 4
2 +2 = 4
4 = 4
Yes x and y is the solution of this equation.
