The value of k for which the system of equation x+3y-4=0 and 2x+ky=7 is inconsistent

Answer»

Answer:

k=6

Step-by-step explanation:

inconsistent means no SOLUTION a1/a2=b1/b2 is not equal to c1/c2

from equation 1 and 2

a1/a2=1/2

b1/b2=3/k

c1/c2= -4/-7  =4/7

a1/a2=b1/b2\neq c1/c2

1/2=3/k\neq 4/7

if k=6

then 3/6 =1/2

therefore 1/2=1/2\neqc1/c2

when we substitute k=6 3 and 6 gets CANCELLED where it becomes 1/2 then the formula will be satisfied.
