Question

Find the value of ‘k’ for which the system of linear equations x + 2y = 3, 5x + ky +7 =0 is inconsistent.b​

Answer 1

Answer:

The given equation x+2y-3=0 and 5x+ky+7=0

it is form of ax²+bx+c=0

1. here a¹=1,b¹=2,c¹=-3 and a²=5,b²=k, c³=7(here123 mean number )

a¹/b¹=1/5

b¹/b²=2/k

c¹/c²=-3/7

then value of k=

1/5=2/k

=k=10 Answer
