(3 x-4 5 ) =25

(0 1 3 )

a) find the value of x

b) hence ,find (-2 1 x+2 )^-1

( 3 x-4 5 )

(o 1 3 )

p/s : all the value above IS COMBINE in one bracket ( )

- math (Matrix algebra) -
**fizz**, Wednesday, April 16, 2014 at 3:42amsolve the equations by using

a) the adjoint matrix

b) elementary row operations

i) x+y+z=6

2x-y+z=3

x+4y-z=6

ii) 3p-3q+r=1

-3p+5q-2r=-1

p-2q+r=3

iii)-12a+b+17c=-14

2a-b+3c=5

8a+b-13c=-3

thanks sir/madam
