Question

For what value of 'K' the pair of Linear equations 2x+y+3 = 0 and
4x+2y+k = 0 represents coincident lines.​

Answer 1

Answer:

k=6 is your answer Dear

Step-by-step explanation:

In collinear lines:-

$\frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2}$

hence

$\frac{b1}{b2} = \frac{c1}{c2}$

$\frac{y}{2y} = \frac{3}{k}$

$\frac{1}{2} = \frac{3}{k}$

$k = 6$
