2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =

2x-3y+5z=16, 3x+ 2y-4z= -4, x + y - 2z =- 3.

Add: 5x - 8y + 2z, 3z - 4y - 2x, 6y - z - x and 3x - 2z - 3y

Solve the following equations by the method of inversion: 5x-y+4z = 5 , 2x+3y+5z = 2 and 5x-2y+6z = -1 .

Using matrices , solve the following system of linear equations 5x -y + 4z =5 2x + 3y + 5z =2 5x -2y + 6z =-1
