12x=6-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{12x}{12}=\frac{6-3y}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{6-3y}{12}
Mā te whakawehe ki te 12 ka wetekia te whakareanga ki te 12.
x=-\frac{y}{4}+\frac{1}{2}
Whakawehe 6-3y ki te 12.
3y=6-12x
Tangohia te 12x mai i ngā taha e rua.
\frac{3y}{3}=\frac{6-12x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{6-12x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=2-4x
Whakawehe 6-12x ki te 3.
