Kua tāruatia ki te papatopenga
2x+15y=2
Whakareatia te 5 ki te 3, ka 15.
2x=2-15y
Tangohia te 15y mai i ngā taha e rua.
\frac{2x}{2}=\frac{2-15y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{2-15y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{15y}{2}+1
Whakawehe 2-15y ki te 2.
2x+15y=2
Whakareatia te 5 ki te 3, ka 15.
15y=2-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{15y}{15}=\frac{2-2x}{15}
Whakawehea ngā taha e rua ki te 15.
y=\frac{2-2x}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
