restamos ecuacion 1 y 2,para eliminar z,lo que resulte sera ecuacion 4despues;restamos ecuacion 2 y3,para eliminar z,lo que resulte sera ecuacion 5
1(2x-y+2z=6)............2x-y+2z=6 2(3x+2y-z=4).............6x+4y-2z=8 8x+3y=14 ecuacion 4
-3(3x+2y-z=4).............-9x-6y+3z= -12 1(4x+3y-3z=1)..............4x+3y-3z=1 -5x-3y= -11 ecuacion 5
restamos ecuacion 4 y 5
8x+3y=14-5x-3y= -11 3x=3.......x=3/3.........x=1
si x=1
8x+3y=148(1)+3y=148+3y=143y=14-83y=6y=6/3y=2
si x=1 y=22x-y+2z=62(1)-2+2z=62-2+2z=62z=6z=6/2z=3
rpta: x=1 y=2 z=3
