Question

For what the value of K the following system of equation are parallel 2x+ky=10, 3x+(k+3)y=12

Answer 1

Answer:

6

Step-by-step explanation:

the condition for parallel lines is

a1/ a2 = b1/b2

2/3 = k/k+3

cross multiplication

3k = 2 ( k+3)

3k = 2k +6

3k - 2k = 6

k = 6

hope this helps you..

Answer 2

Answer:

k=6

Step-by-step explanation:

a1/a2=b1/b2

2/3 = k/k+3

now, by cross multiplication :-

3k = 2(k+3)

3k = 2k + 6

3k - 2k = 6

《k = 6》
