Question

for what value of k the given pair of linear equations are parallel Kx+3y=5, 4x+6y= 13​

Answer 1

Step-by-step explanation:

a1/a2=K/4

b1/b2=3/6

c1/c2=5/13

Condition for parallel line is

a1/a2=b1/b2≠c1/c2

put values

K/4=3/6≠5/13

Dont do anything to 3rd which is not equal to

equalies 1st and 2nd

K/4=3/6

by cross multiplication

k=4*3/6

k=12/6

k=2
