Kua tāruatia ki te papatopenga
x=5-2x_{50}+3
Me tāpiri te 3 ki ngā taha e rua.
x=8-2x_{50}
Tāpirihia te 5 ki te 3, ka 8.
5-2x_{50}=x-3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x_{50}=x-3-5
Tangohia te 5 mai i ngā taha e rua.
-2x_{50}=x-8
Tangohia te 5 i te -3, ka -8.
\frac{-2x_{50}}{-2}=\frac{x-8}{-2}
Whakawehea ngā taha e rua ki te -2.
x_{50}=\frac{x-8}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x_{50}=-\frac{x}{2}+4
Whakawehe x-8 ki te -2.
