find k if kx +2y=6 and x=-1 and y = 2

{\huge{\underbrace{\rm{Answer}}}}

Given:

  • x = – 1
  • y = 2

To find:

Find the value of K

Solution:

The given equation is kx +2y=6

Now,

put the value of x and y

\sf{\implies kx +2y=6}

\sf{\implies k×(-1)+2×2=6}

\sf{\implies -k+4=6}

\sf{\implies -k=6-4}

\sf{\implies -k=2}

\boxed{\bf{\pink{K=-2}}}

Therefore,the value of k is – 2
