Question

if two lines are given to be parallel .the equation of the two lines are 4 x + 3 y= 14 and 12 x + k y = 28 find the value of k ​

Answer 1

Answer:

If the lines are parallel then slope will be equal.

$- \frac{4}{3} = - \frac{12}{k} \\ \\ 4k = 36 \\ \\ k = 9$

Answer 2

Answer:

K=2

Step-by-step explanation:

4x+3y=14,-12x+(-ky)=-28 = - 8-3k=-14,-3k=--14+8, - 3k=-6, k=2
