6x=y-5y
Tangohia te 5y mai i ngā taha e rua.
6x=-4y
Pahekotia te y me -5y, ka -4y.
\frac{6x}{6}=-\frac{4y}{6}
Whakawehea ngā taha e rua ki te 6.
x=-\frac{4y}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=-\frac{2y}{3}
Whakawehe -4y ki te 6.
5y+6x-y=0
Tangohia te y mai i ngā taha e rua.
4y+6x=0
Pahekotia te 5y me -y, ka 4y.
4y=-6x
Tangohia te 6x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{4y}{4}=-\frac{6x}{4}
Whakawehea ngā taha e rua ki te 4.
y=-\frac{6x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{3x}{2}
Whakawehe -6x ki te 4.
