Question

find the values of a,b,c and d when [a+3 4 -2 b-6] = [-1 c-3 d+1 2] (matrices)​

Answer 1

A=-4, b=8,c=7,d=-3

Acc. To me,

You see the both matrix are order 1*3

So it is given both are equal

So just equal element of first row and 1st column to another matrix.simlarly 1 row and 2nd column and...

You found

a+3=-1 then a=-4

4=c-3 then c=7

-2=d+1 then d=-3

b-6=2 then b=8.

I hope it help
