Question

For what value of K, system of equation − − =
and + − = , have unique solution.

Answer 1

Step-by-step explanation:

For unique solution, we know that lines will intersect at only one point.

And here we have the condition that

$\frac{a1}{b1} not = \frac{a2}{b2}$

putting value in this eq

we will get

k not= any real no.

therefore at the end we will write that

k can have any real value except the one which we found from above.
