inverso aditivo
[tex] \frac{6}{5} = \frac{z}{ - 5} \\ \\ z = 6 \\ \\ \frac{6}{5} = \frac{6}{ - 5} = 0[/tex]
inverso multiplicativo
[tex] \frac{6}{5} = \frac{z}{6} \\ \\ z = 5 \\ \\ \frac{6}{5} \times \frac{5}{6} = 1[/tex]
[tex] \frac{4}{4} = \frac{x}{ - 4} \\ \\ x = 4 \\ \\ \frac{4}{4} = \frac{4}{ - 4} = 0[/tex]
[tex] \\ \frac{4}{4} \times 1 = 1[/tex]
