Question

is the pair of linear equation given by 3 X + 2 K Y is equal to 2 and 2 X + 5 Y + 1 is equal to zero represent Parallel Lines then find the value of k​

Answer 1

Answer:

3x + 2ky - 2 =0

2x + 5y -0 = 0

. : here, a1= 3    b1=2k     c1=-2

             a2=2    b2=5      c2=-0

a1/a2 = b1/b2 ≠ c1/c2

3/2 = 2k/5

3*5=2(2k)

15=4k

k=15/4
