Question

2. For what value of k, the pair of eq. 4x-3y= 9,
2x + ky =11?
=11 has no soll. ?​

Answer 1

Answer:

-3/2

Step-by-step explanation:

A pair of linear equations has no solutions if it satisfies the below condition:

$\frac{a1}{a2} =\frac{b1}{b2} \neq \frac{c1}{c2}$

Here

$\frac{4}{2} =\frac{-3}{k} \neq \frac{9}{11}$

$\frac{4}{2} =\frac{-3}{k}$

4k = -6

k= $\frac{-6}{4}$

k= $\frac{-3}{2}$
