Q6 of 75 Page 8

If and AX = B, then find n.

It is given that


AX = B


Where


A = and B =


And we have to find the value of n.


AX =


or, AX =


Thus,



On comparing both sides we get,


2n+4 = 8 ……………...(i)


4n+3 = 11 ……………...(ii)


From (i),


2n = 4


n = 2


and from (ii) ,


4n = 8


n = 2



Hence
