Whakaoti mō k
k=x-z+200
Whakaoti mō x
x=z+k-200
Tohaina
Kua tāruatia ki te papatopenga
k-x=200-z
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
k=200-z+x
Me tāpiri te x ki ngā taha e rua.
k-x=200-z
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=200-z-k
Tangohia te k mai i ngā taha e rua.
-x=200-k-z
He hanga arowhānui tō te whārite.
\frac{-x}{-1}=\frac{200-k-z}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{200-k-z}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=z+k-200
Whakawehe 200-z-k ki te -1.
