Step-by-step explanation:

ANSWER:-

We know that:-

If it contains infinite solutions, then the equation stands as:-

\dfrac{a1}{a2} = \dfrac{b1}{b2} = \dfrac{c1}{c2}

a2

a1

=

b2

b1

=

c2

c1

In this we have :-

a1 as 2

a2 as 4

b1 as 3

b2 as k

c1 as 5

c2 as 10

We need to place the equations.

If I consider first 2, it stands:-

\dfrac{2}{4} = \dfrac{3}{k}

4

2

=

k

3

2k = 122k=12

\boxed{k = 6}

k=6

Now, let us verify our answer with second pair.

\dfrac{3}{k} = \dfrac{5}{10}

k

3

=

10

5

5k = 305k=30

\boxed{k = 6}

k=6

So, K = 6 is the answer.

More to know:-

If no solutions, then:-

\dfrac{a1}{a2} = \dfrac{b1}{b2} \neq \dfrac{c1}{c2}

a2

a1

=

b2

b1

≠

c2

c1
