Answer 1

Answer:

answer is k=12/5

Step-by-step explanation:

we know  that non zero solution will be infinte many solution

so,  $a{1}/ a{2}$=$b_{1}/b_{2}$=$c_{1} /c_{2}$

5/4=3/k

5(k)=4(3)

5k=12

k=12/5

Answer 2

Given :-

• $\tt \: 5x-3y=0 \\ </li><li></li><li> \tt4x+ky=0$

To Find :-

• $\tt \: The \: value \: of \: \red k.$

Solution :-

$\mapsto \tt\: 5x-3y=0 \\ </p><p></p><p> \mapsto \tt4x+ky=0$

$\tt \: Here,$

$\mapsto\tt \: a_1 = 5, \: b_1 = - 3, \: c_1 = 0</p><p></p><p></p><p></p><p></p><p>$

$\mapsto \: \tt \: a_2= 4, \: b_2= k, \: c_2= 0$

$\tt \: Now,$

${\tt{ \boxed{ \tt{ \frac{a_1}{a_2 } = \frac{b_1}{b_2} }}}}$

$\tt \: putting \: values \:$

$\tt \mapsto \: \frac{5}{4} = \frac{ - 3}{k}$

$\tt \mapsto \:5k = - 12$

$\tt \mapsto \:k = \frac{ - 12}{5}$

$\huge\tt \:{ \boxed{ \tt{ \blue{k = - 2.4}}}}$

Hence,

• The value of k is -2.4 .
