Question

Find the value of k, if x = -1 and y = 2 is a solution of kx + 3y = 7.

Answer 1

Answer:

k= -6. The answer will be correct.

Answer 2

Answer:

$\huge{\boxed{\rm{\red{K=-1}}}}$

Step-by-step explanation:

Given equation is Kx+3y=7

Put x=-1 and y=2 in the given equation then

=>k(-1)+3(2)=7

=>-k+6=7

=>-k=7-6

=>-k=1

=>k=-1

The value of k is -1
