Question

for what value of k do dependent linear equations x+2y=4 and 3x+ky=12 represent coincident line​

Answer 1

Answer:

Step-by-step explanation:

the value of k is 6 so that they are coincide lines

Answer 2

Given; x+2y=4 and 3x+ky=12

To Find; for what value of k do dependent linear equations x+2y=4 and 3x+ky=12 represent coincident line

Solution;

x+2y=4 and 3x+ky=12

a1=1,b1=4 and a2=3, b2=k

for coincident lines

a1/a2=b1/b2=c1/c2

1/4=3/k

k=3/4

Hence the value of k is 3/4
