Question

2. For what value of k, the following system of equations will be inconsistent:
4x + 6y = 11; 2x + ky = 7

Answer 1

check a1/a2=b1/b2 not equal to c1/c2

Answer 2

Answer:

If a1/a2=b1/b2 is not equal to c1/c2

So on compairind:a1=4,b1=6,c1=-11

and a2=2,b2=k,c2=-7

4/2=6/k

So, on cross multiplying, 4*k=6*2

4k=12

k=3.Hope u understand
