Question

find the value of k if (2, 3 ) is a solution of the equation 3x - y + k =0 *​

Answer 1

       $\underline{\bold{Solution:}}$

       $\text{It is given that }(2,3) \text{ is the solution of the equation }3x - y + k = 0$

$\implies 3(2) - 3 + k = 0$

       $\text{Simplifying...}$

$\implies 6 - 3 + k = 0$

       $\text{Simplifying...}$

$\implies 3 + k = 0$

       $\text{Transposing 3 to R.H.S}$

$\implies \boxed{k = -3}$
