Question

Find the value of cake if the pair of equations 5x+ky+8=0 and 10x+14y+12y=0 as no solution?

Answer 1

Answer: k = 7

Step-by-step explanation:

I assume the question is 5x+ky+8=0 and 10x+14y+12=0

When (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution.

a1 = 5                  b1 = k                             c1 = 8

a2 = 10                b2 = 14                          c2 = 12

5/10 = k/14

1/2 = k/14

k/14 = 1/2

k = 14/2

k = 7
