Question

for what value of k will the following system have unique solution 2x+3y=4,(k+2)x+6y=3k+2​

Answer 1

Explanation:

2x+3y=4, (k+2)x+6y=3k+2

According to the question, the following equations have a unique solution.

So, a1/a2is not equal to b1/b2.

a1=2, b1=3 and a2=k+2, b2=6

a1/a2=1/k+2 and b1/b2=k+2/6

therefore when k=6 the equations have a unique solution.....
