चरण 3

Use the result matrix to declare the final solution to the system of equations.

x_{1} + 4 x_{2} + 3 x_{4} = 0

$x_{1} + 4 x_{2} + 3 x_{4} = 0$

x_{3} - 3 x_{4} = 0

$x_{3} - 3 x_{4} = 0$

x_{5} = 0

$x_{5} = 0$

चरण 4

Write a solution vector by solving in terms of the free variables in each row.

[\begin{array}{c} x_{1} \\ x_{2} \\ x_{3} \\ x_{4} \\ x_{5} \end{array}] = [\begin{array}{c} - 4 x_{2} - 3 x_{4} \\ x_{2} \\ 3 x_{4} \\ x_{4} \\ 0 \end{array}]

$[\begin{array}{c} x_{1} \\ x_{2} \\ x_{3} \\ x_{4} \\ x_{5} \end{array}] = [\begin{array}{c} - 4 x_{2} - 3 x_{4} \\ x_{2} \\ 3 x_{4} \\ x_{4} \\ 0 \end{array}]$

चरण 5

Write the solution as a linear combination of vectors.

[\begin{array}{c} x_{1} \\ x_{2} \\ x_{3} \\ x_{4} \\ x_{5} \end{array}] = x_{2} [\begin{array}{c} - 4 \\ 1 \\ 0 \\ 0 \\ 0 \end{array}] + x_{4} [\begin{array}{c} - 3 \\ 0 \\ 3 \\ 1 \\ 0 \end{array}]

$[\begin{array}{c} x_{1} \\ x_{2} \\ x_{3} \\ x_{4} \\ x_{5} \end{array}] = x_{2} [\begin{array}{c} - 4 \\ 1 \\ 0 \\ 0 \\ 0 \end{array}] + x_{4} [\begin{array}{c} - 3 \\ 0 \\ 3 \\ 1 \\ 0 \end{array}]$

चरण 6

Write as a solution set.

{x_{2} [\begin{array}{c} - 4 \\ 1 \\ 0 \\ 0 \\ 0 \end{array}] + x_{4} [\begin{array}{c} - 3 \\ 0 \\ 3 \\ 1 \\ 0 \end{array}] | x_{2}, x_{4} \in R}

${x_{2} [\begin{array}{c} - 4 \\ 1 \\ 0 \\ 0 \\ 0 \end{array}] + x_{4} [\begin{array}{c} - 3 \\ 0 \\ 3 \\ 1 \\ 0 \end{array}] | x_{2}, x_{4} \in R}$
