General Solution-Three variables-Two Equations

  1. Mar 17, 2012 #1
    1. The problem statement, all variables and given/known data

    Find the general solution of the following set of equations:

    u − w + y = 1
    u + w + 2y = 0

    2. Relevant equations



    3. The attempt at a solution

    I know that the solution is in this form (u,w,y)= (a,b,c) + k*(d,e,f)

    Can you please explain me how i am going to find it?

    hi mikael27! :smile:

    there are several ways to do this

    one is to see that each equation represents a plane (in ordinary 3D space)

    so their intersection is a line

    how would you find the direction of that line? :wink:
