( y = \frac { 23 x } { 100 } + 0.25 )
Whakaoti mō x
x=\frac{100y-25}{23}
Whakaoti mō y

Kua tāruatia ki te papatopenga
\frac{23x}{100}+0.25=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{23x}{100}=y-0.25
Tangohia te 0.25 mai i ngā taha e rua.
23x=100y-25
Whakareatia ngā taha e rua o te whārite ki te 100.
\frac{23x}{23}=\frac{100y-25}{23}
Whakawehea ngā taha e rua ki te 23.
x=\frac{100y-25}{23}
Mā te whakawehe ki te 23 ka wetekia te whakareanga ki te 23.
