Unformatted text preview: From the reduced row echelon form of the augmented matrix, x 1 , x 2 are basic variables and x 3 , x 4 are free variables. The general solution is x 1 = 5 x 3 + 7 x 4 , x 2 =2 x 36 x 4 , x 3 , x 4 are free . Thus, the parametric vector form is x = 5 x 3 + 7 x 42 x 3 + 6 x 4 x 3 x 4 = 5 x 32 x 3 x 3 + 7 x 4 +6 x 4 x 4 = x 3 52 1 + x 4 7 6 1 . 1...
