Kua tāruatia ki te papatopenga
2x+2y=y
Whakareatia ngā taha e rua o te whārite ki te 2.
2x=y-2y
Tangohia te 2y mai i ngā taha e rua.
2x=-y
Pahekotia te y me -2y, ka -y.
\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.
2x+2y=y
Whakareatia ngā taha e rua o te whārite ki te 2.
2x+2y-y=0
Tangohia te y mai i ngā taha e rua.
2x+y=0
Pahekotia te 2y me -y, ka y.
y=-2x
Tangohia te 2x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
