Kua tāruatia ki te papatopenga
\pi -2x=2-3
Tangohia te 3 mai i ngā taha e rua.
\pi -2x=-1
Tangohia te 3 i te 2, ka -1.
-2x=-1-\pi
Tangohia te \pi mai i ngā taha e rua.
-2x=-\pi -1
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{-\pi -1}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{-\pi -1}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{\pi +1}{2}
Whakawehe -1-\pi ki te -2.
