12x=17-4y
Tangohia te 4y mai i ngā taha e rua.
\frac{12x}{12}=\frac{17-4y}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{17-4y}{12}
Mā te whakawehe ki te 12 ka wetekia te whakareanga ki te 12.
x=-\frac{y}{3}+\frac{17}{12}

4y=17-12x
Tangohia te 12x mai i ngā taha e rua.
\frac{4y}{4}=\frac{17-12x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{17-12x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=\frac{17}{4}-3x
Whakawehe 17-12x ki te 4.
