Kua tāruatia ki te papatopenga
-9z-72=-9z-72
Whakamahia te āhuatanga tohatoha hei whakarea te -9 ki te z+8.
-9z-72+9z=-72
Me tāpiri te 9z ki ngā taha e rua.
-72=-72
Pahekotia te -9z me 9z, ka 0.
\text{true}
Whakatauritea te -72 me te -72.
z\in \mathrm{C}
He pono tēnei mō tētahi z ahakoa.
-9z-72=-9z-72
