$x + z = 4$ , $y = - 2$

解题步骤 1

Write the system as a matrix.

$[\begin{array}{c} 1 & 0 & 1 & 4 \\ 0 & 1 & 0 & - 2 \end{array}]$

解题步骤 2

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

$x + z = 4$

$y = - 2$

解题步骤 3

The solution is the set of ordered pairs that make the system true.

$(4 - z, - 2, z)$
