Whakaoti mō z
z=-3
Tohaina
Kua tāruatia ki te papatopenga
\frac{42}{-7}=z-3
Whakawehea ngā taha e rua ki te -7.
-6=z-3
Whakawehea te 42 ki te -7, kia riro ko -6.
z-3=-6
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
z=-6+3
Me tāpiri te 3 ki ngā taha e rua.
z=-3
Tāpirihia te -6 ki te 3, ka -3.
