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