Question

if 2x=3y+5=0 kx+6y+7=00 are parallel then find the value of k

Answer 1

Answer:

k = -4

Step-by-step explanation:

2x - 3y = -5

kx + 6y = -7

a1/a2 = b1/b2 ≠ c1/c2

2/k = -3/6 ≠ 5/7

k = 6 * 2 / -3

k = -4

Answer 2

Answer:

k=4

explanation:

Given 2 equations:2x+3y+5=0

kx+6y+7=0a1=2, a2=k, b1=3, b2=6, c1=5, c2=7

Condition for paralell lines-

a1/a2 = b1/b2

Putting values-

2/k=3/62

2/k=1/2

k=2×2

k=4
