Hi,

-3x-2y+3z= -1                0r z+=+%283x%2B2y+-+1%29%2F3)

 2x+5y-3z= -6

  -x+ 3y = -7                0r x+=+3y%2B+7

 

  4x+3y+3z= 22 

 2x+5y-3z = -6

    6x + 8y = 16



  -x+ 3y = -7         |multiplying 1st EQ by 6 and adding to 2nd EQ to eliminate x 

6x+ 8y = 16

      26y = -26

        y = -1  and x = 4  and z = 3
