Answer:

⇢kx+2y=6

\dashrightarrow \blue{x=-1}⇢x=−1

\dashrightarrow \blue{y=2}⇢y=2

\large\underline\mathfrak{\red{TO\:FIND,}}

TOFIND,

\dashrightarrow \blue{The\:value\:of\:k}⇢Thevalueofk

\large\underline\bold{\pink{\mathfrak{SOLUTION,}}}

SOLUTION,

\implies \green{kx+2y=6}⟹kx+2y=6

\therefore \orange{putting\:the\:value\:of\:x\:and\:y\:.}∴puttingthevalueofxandy.

\implies \purple{k(-1)+2(2)=6}⟹k(−1)+2(2)=6

\implies \purple{-k+4=6}⟹−k+4=6

\implies \purple{-k=6-4}⟹−k=6−4

\implies \purple{-k=2}⟹−k=2

\implies \purple{k=-2}⟹k=−2

\rm{\boxed{\bf{\circ\:\: k=-2\:\: \circ }}}

K = 2
