有限数学示例

$a \cdot 1 = 3$ , $r = - 3$

解题步骤 1

将 $a$ 乘以 $1$ 。

$a = 3$

$r = - 3$

解题步骤 2

Write the system as a matrix.

$[\begin{array}{c} 1 & 0 & 3 \\ 0 & 1 & - 3 \end{array}]$

解题步骤 3

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

$a = 3$

$r = - 3$

解题步骤 4

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

$(3, - 3)$
