Tohaina
Kua tāruatia ki te papatopenga
-2y+5=9
Whakaarohia te whārite tuatahi. Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2y=9-5
Tangohia te 5 mai i ngā taha e rua.
-2y=4
Tangohia te 5 i te 9, ka 4.
y=\frac{4}{-2}
Whakawehea ngā taha e rua ki te -2.
y=-2
Whakawehea te 4 ki te -2, kia riro ko -2.
y=-2 z=-2 a=-2 b=-2 c=-2 d=-2
Kua oti te pūnaha te whakatau.
