Hey Vishal ,

Hope u r doing well !

If x = – 2 and y = 3 is the solution of the equation 3x – 5y = k, then the value of ‘k’ is ?

$\huge\red{\boxed{Answer}}$

If we substitute the given values of x and y in the equation, we will get the value of k.

$3x - 5y = k$

$x = ( - 2) \\ y = 3 \: \: \: \: \: \: \:$

$3( - 2) - 5(3) = k$

$( - 6) - 15 = k$

$- 21 = k$

$\large{\boxed{The \: value \: of \: k \: is \: (-21)}}$

$Hope \: \: this \: \: helps \: \: you \: !$

Answer 2

$\LARGE{ \underline{\underline{\sf{In\:this\:question:}}}}$

3x - 5y = k

x = (-2)

y = 3

$\huge\boxed{Solution}$

3×(-2) - 5×3 = k

k = (-6) - 15

k = -21

$\tt\pink{Therefore\:the\:value\:of\:k\:is\:-21}$
