Answer :


To find: - x , y , z


Given set of lines are : -


2x + 3y + 3z = 5;


x – 2y + z = - 4;


3x – y – 2z = 3


Converting the following equations in matrix form,


AX = B



2R2 – R1


2R3 – 3R1



R3 - 13R2



Again converting into equations we get


2X + 3y + 3z = 5


- 7y - z = - 13


80 y = 160


Y = 2


- 7×2 - z = - 13


Z = - 1


2x + 3×2 + 3× - 1 = 5


2x = 5 - 6 + 3


X = 1
