hii. .....friend!!

the answer is here,

=> kx-5y=2.

=> 6x+2y=7.

There is no solution. So,

a1/a2 = b1/b2.

=> k/6 =-5/2

=> k =6×(-5)/2

=> -15.


:-)Hope it helps u

Heya dear !!!!



KX - 5 = 2 -------(1)



6X + 2Y = 7 -------(2)




These equations are of the form of A1X + B1Y + C1 = 0 And A2X + B2Y + C2 = 0.



Where,



A1 = K , B1 = -5 and C1 = -2


And,



A2= 6 , B2 = 2 and C2 = -7



It is given that the given equations has no solution.



For no solution we must have;


A1/A2 = B1/B2 not equal C1/C2


K/6 = -5/2 not equal -2/-7






2K = -30




K = -30/2 => -15
