Question

For which value of k the linear
equations x – 3y = 7 and kx + 6y = 5 have
no solution?​

Answer 1

Answer:

k = -2

Step-by-step explanation:

Parallel lines don't have a meeting point

ax + by + c1 = 0

ax + by + c2 = 0

are parallel lines because they have equal slopes

line1 :

m1 = -a / b  intercept = -c1/a

line 2:

m2 = -a / b intercept = -c2/a

to find k simply equate m1 and m2

1/-3 = k/6

k = -2
