Whakaoti mō x
x=\frac{-z-5}{2}
Whakaoti mō z
z=-2x-5
Tohaina
Kua tāruatia ki te papatopenga
-2x=z+5
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{z+5}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{z+5}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{-z-5}{2}
Whakawehe 5+z ki te -2.
5+z=-2x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
z=-2x-5
Tangohia te 5 mai i ngā taha e rua.
Ngā Tauira
whārite tapawhā
