Answer 1

${\bold{\huge{\underline{\blue{\sf{Question:}}}}}}$

${\bold{\sf{The \:value\: of\: k\: for \:which \:(1, - 3 ) \:is \:a \:solution }}}$

${\bold{\sf{of\: the\: equation\: – 4x + ky = 5\: is...}}}$

${\bold{\huge{\underline{\pink{\sf{To \: Find:}}}}}}$

${\bold{\sf{The \: value \: of \: ‘k’}}}$

${\bold{\huge{\underline{\green{\sf{Solution:}}}}}}$

${\bold{\sf{-4x+ky = 5}}}$

Here, (1,-3) is a solution

So, x = 1 and y = -3

${\bold{\sf{-4(1)+k(-3) = 5}}}$

${\bold{\sf{-4-3k = 5}}}$

${\bold{\sf{3k = -9}}}$

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

Answer 2

Answer:

-3

Step-by-step explanation:

we can put the coordinates of that point in the equation and get the ans...

-4(1)+k(-3)=5

-3k=9

k=-3
