[(" iii) ",x+y+z=3],[,x+2y+3z=4],[,x+4y+9z=6]

Use matrix to solve the following system of equations. x+y+z=3 x+2y+3z=4 x+4y+9z=6

Find the values of x, y and z from the following equations:(i) [[4, 3],[x,5]]=[[y, z],[1, 5]] (ii) [[x+y,3],[ 5+z, x y]]=[[6, 3],[ 5 ,8]] (iii) [[x+y+z],[ x+z],[ y+z]]=[[9],[ 5],[ 7]]

3x+4y+7z=4, 2x+y+ 3z= 3, x + 2y +3z =8.

The following system of linear equations has x+ 2y + 3z=1,2x + y + 3z = 2, 5x+ 5y + 9z = 4

If P,Q and R are the values of x,y and z respectively, which satisfy the system of equations x+y+z =6,x+2y+3z=14 and x+4y+9z=36, then P+R-Q=

By using Cramer's solve x+y+z=1,2x+2y+3z=6,x+4y+9z=3

2x-y+z=6,x+2y+3z=3,3x+y-z=4
