Whakaoti i te z=x-87.3/12

$$z = \frac { x - 87.3 } { 12 }$$

Whakaoti mō x

$$x=12z+87.3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ia wā o x-87.3 ki te 12, kia riro ko \frac{1}{12}x-7.275.

$$z=\frac{1}{12}x-7.275$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{1}{12}x-7.275=z$$

Me tāpiri te 7.275 ki ngā taha e rua.

$$\frac{1}{12}x=z+7.275$$

Me whakarea ngā taha e rua ki te 12.

$$\frac{\frac{1}{12}x}{\frac{1}{12}}=\frac{z+7.275}{\frac{1}{12}}$$

Mā te whakawehe ki te \frac{1}{12} ka wetekia te whakareanga ki te \frac{1}{12}.

$$x=\frac{z+7.275}{\frac{1}{12}}$$

Whakawehe z+7.275 ki te \frac{1}{12} mā te whakarea z+7.275 ki te tau huripoki o \frac{1}{12}.

$$x=12z+87.3$$

Whakaoti mō z

$$z=\frac{x}{12}-7.275$$
