Hit and Trial.
This question is way to easier if you do it with the add maths.

Question 25 b part.

uss ne kaha hai integer btao jo c ke sab se karib hai!

sove kernay ke zaroorat nai hai

graph se deikh lo!
and (9,3) is the closest one

 

[Fate0]

how did u find out the value of x

FE = X ( FD)

-p+q = X ( 3p + k(2q - 4p) )

-p+q = X (p (3-4k) + 2kq) )

-p + q = Xp (3-4k) + 2Xkq

In addmaths we can compare coefficient of P and Q.

-1 = X(3-4k)

1 = 2Xk

Form two simultaneous. Substitute. and you get 1.5 of K.

CAN ANYBODY EXPLAIN BOTH OF THESE QUESTIONS TO ME..

 

[FLRNAB]

Yeh FE kay sath 3 kahan se aya?

FLRNAB How do you deduce the factor by which vector FE is to be multiplied???

K is a numeric value so it can't contain any variables. FD is greater than FE so K must be positive.
