Kua tāruatia ki te papatopenga
3x=9-5y
Tangohia te 5y mai i ngā taha e rua.
\frac{3x}{3}=\frac{9-5y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{9-5y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=-\frac{5y}{3}+3
Whakawehe 9-5y ki te 3.
5y=9-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{5y}{5}=\frac{9-3x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{9-3x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
