Kua tāruatia ki te papatopenga
6x=12-2y
Tangohia te 2y mai i ngā taha e rua.
\frac{6x}{6}=\frac{12-2y}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{12-2y}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=-\frac{y}{3}+2
Whakawehe 12-2y ki te 6.
2y=12-6x
Tangohia te 6x mai i ngā taha e rua.
\frac{2y}{2}=\frac{12-6x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{12-6x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=6-3x
Whakawehe 12-6x ki te 2.
