Resposta:

Explicação passo-a-passo:

• $\left \[[ {{4} \atop {3}}\left\ {0}\atop {-1}}\right.]\right\left [\[x} \atop {y}} \right]=[\left \ {6} \atop {9}\right.]\\\\\left \{ {{4x+0y=6} \atop {3x-y=9}} \right. \\\\4x=4\\x=3/2\\\\3.3/2-y=9\\\\9-2y=18\\\\2y=-9\\\\y=-9/2\\\\X=\left \[[ {{3/2} \atop {-9/2}} \right.]$
