Question

If x = 2k - 1 and y = k is a solution of the equation x - 5y + 6 = 0, find the value of k

Answer 1

Answer:

K = 5/3

Step-by-step explanation:

put x= 2k-1 and y=k in the equation

2k-1-5k+6=0

-3k+5=0

-3k=-5

k=-5/-3

K=5/3

Answer 2

Answer :

The value of ' K ' is 5/3.

Explanation :

If x = ' 2k - 1 ' and y = ' k ' is a solution of the equation x - 5y + 6 = 0 then substitute the value of ' x ' and ' y ' in the equation.

we get,

$\sf x - 5y + 6 = 0$

$\sf\implies 2k - 1 - 5 (k) + 6 = 0$

$\sf\implies 2k - 5k + 6 -1 = 0$

$\sf\implies 2k - 5k + 5 =0$

$\sf\implies -3k + 5 = 0$

$\sf\implies k = \dfrac{-5}{-3}$

$\sf\therefore k = 5/3$

Hence, The value of k is 5/3
