Question

(B) (i) Write down the condition for which the following pair of linear equation will
have no solution and find the value of k. (2)
KX-5y = 2
6x + 2y = 7​

Answer 1

Step-by-step explanation:

ax1 + by1 = C1 ..........(i)

ax2+by2 =C2......(i)

if two equation has no sollution then it satisfy this condition–

a1 /a2 = b1 / b2 ≠ c1 / c2

KX-5y = 2

6x + 2y = 7

now in the question....we apply this condition..

a1=X , a2=6 , b1= –5 , b2= 2

x /6 = –5 / 2

=⟩ x = (–30) / 2

=⟩ x= –15
