Whakaoti mō z
z=69
Tohaina
Kua tāruatia ki te papatopenga
16\times 4=-5+z
Me whakarea ngā taha e rua ki te 4.
64=-5+z
Whakareatia te 16 ki te 4, ka 64.
-5+z=64
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
z=64+5
Me tāpiri te 5 ki ngā taha e rua.
z=69
Tāpirihia te 64 ki te 5, ka 69.
