hkus10 Posted January 19, 2011 Share Posted January 19, 2011 solve each given linear system by the method of elimination 2x-3y+4z=-12 x-2y+z=-5 3x+y+2z=1 How to solve this problem. What should I do first? Link to comment Share on other sites More sharing options...
CaptainPanic Posted January 19, 2011 Share Posted January 19, 2011 To make a long story short, click here, for help from wikipedia. There are other methods (here, again wikipedia) which do essentially the same. Link to comment Share on other sites More sharing options...
HamsterPower Posted January 20, 2011 Share Posted January 20, 2011 solve each given linear system by the method of elimination2x-3y+4z=-12 x-2y+z=-5 3x+y+2z=1 How to solve this problem. What should I do first? at first, it seems really complicated but once you get it , you will know it forever so anyways keep in mind that if you have 3 unknown variables you need 3 equations to solve it. Which you have right now Method of elimination is solving the unknown by eliminating the unnecessary variables For example, if you want to find x, you will need to eliminate y and z When i mean by eliminating , it is like making them 0 3-3 is zero rite? so is 3x-3x = 0 Link to comment Share on other sites More sharing options...
