x+2y-2z=5,3x-y+z=8,x+y-z=4

Add : 8x - 3y + 7z, -4x + 5y - 4z, -x - y - 2z

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

4x -5y-11z=12,. x-3y+z=1 2x + 3y-7z = 2

Solve the system: x + y - 2z = 0, 2x - 3y + z = 0, 3x - 7y + 10z = 0, 6x - 9y + 10z = 0.

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]]

Which of the following equations are consistent? If consistent, find their solutions. {:(x - 3y - 8z = -10),(3x + y - 4z = 0),(2x + 5y + 6z = 13):}
