Tohaina
Kua tāruatia ki te papatopenga
3-x_{1}=e
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x_{1}=e-3
Tangohia te 3 mai i ngā taha e rua.
\frac{-x_{1}}{-1}=\frac{e-3}{-1}
Whakawehea ngā taha e rua ki te -1.
x_{1}=\frac{e-3}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x_{1}=3-e
Whakawehe e-3 ki te -1.
