Homework Statement
Solve the following system of equations:
2x1 - 2x2 -3x3 = -2
3x1 -3x2 -2x3 + 5x4 = 7
x1 - x2 -2x3 -x4 = -3
Homework Equations
The Attempt at a Solution
Ok so I solved the system and got:
x1 -x2 = 5
x3 = 4
x4 = 0
so I've got a point (5,0,4,0) but the answer is r(1,1,0,0) + s(-3,0,-2,1) + (5,0,4,0)
How do I get the other vectors?
