Here is the answer =>

Step-by-step explanation:

Equation =>x+3y-k=0

Values=>x=2,y=-1.

=>x+3y-k=0

=>(2)+3(-1)-k=0 (Putting the values).

=>2-3-k=0

=>-1-k=0

=>-k=1

=>k=-1

VERIFICATION =>

=>x+3y-k=0

=>(2)+3(-1)-(-1)=0

=>2-3+1=0

=>-1+1=0

=>0=0

LHS =RHS.

Hence verified.

So the value of k is 1 for x=2 and y=-1 in the equation x+3y-k=0.
