Kua tāruatia ki te papatopenga
4xy=-8x^{2}
Tangohia te 8x^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{4xy}{4x}=-\frac{8x^{2}}{4x}
Whakawehea ngā taha e rua ki te 4x.
y=-\frac{8x^{2}}{4x}
Mā te whakawehe ki te 4x ka wetekia te whakareanga ki te 4x.
y=-2x
Whakawehe -8x^{2} ki te 4x.
