Kua tāruatia ki te papatopenga
-x=2a
Pahekotia te 2x me -3x, ka -x.
2a=-x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2a}{2}=-\frac{x}{2}
Whakawehea ngā taha e rua ki te 2.
a=-\frac{x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
-x=2a
Pahekotia te 2x me -3x, ka -x.
\frac{-x}{-1}=\frac{2a}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{2a}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=-2a
Whakawehe 2a ki te -1.
