Question

find k if kx +2y=6 and x=-1 and y =2​

Answer 1

Step-by-step explanation:

k×1+2×2=6

k×1+4=6

k=6-4

k=2

Answer 2

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\dashrightarrow kx+2y=6$

$\dashrightarrow x=-1$

$\dashrightarrow y=2$

$\large\underline\bold{TO\:FIND,}$

$\dashrightarrow The\:value\:of\:k$

$\large\underline\bold{SOLUTION,}$

$\implies kx+2y=6$

$\therefore putting\:the\:value\:of\:x\:and\:y\:.$

$\implies k(-1)+2(2)=6$

$\implies -k+4=6$

$\implies -k=6-4$

$\implies -k=2$

$\implies k=-2$

$\large{\boxed{\bf{\star\:\: k=-2\:\: \star }}}$

$\large\underline\bold{THE\:VALUE\:OF\:k\:IS\:-2}$
