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

Passaggio 1

Moltiplica $a$ per $1$ .

$a = 3$

$r = - 3$

Passaggio 2

Write the system as a matrix.

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

Passaggio 3

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

$a = 3$

$r = - 3$

Passaggio 4

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

$(3, - 3)$
