Question

lfa = 9/4 , find (24 + e) - 2e when value of e is 9/6​

Answer 1

Correct option is C)

If A=[

0

3

2

−4

]

then,

kA=[

0

3k

2k

−4k

]

But it is given that

kA=[

0

2b

3a

24

]

So,

[

0

3k

2k

−4k

]=[

0

2b

3a

24

]

⇒−4k=24

k=−6

3a=2k

3a=−12

a=−4

2b=3k

2b=−18

b=−9
