Question 164800
sure ,lets start with z=2 and substitute that into the other 2 equations..we end up with x+2y+3(2)=6 simplified is x+2y=0  and y+2(2)=0  simplifying we get y=-4
 sinc we know y=-4 we can substitute that into the 2nd equation which was simplified to  x+2y+0  and we get x+2(-4)=0  solving for x we arrive at x=8

so x=8
   y=-4
   z=2
