Kua tāruatia ki te papatopenga
6\times 5=x+2y
Whakareatia te 2 ki te 3, ka 6.
30=x+2y
Whakareatia te 6 ki te 5, ka 30.
x+2y=30
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=30-2y
Tangohia te 2y mai i ngā taha e rua.
6\times 5=x+2y
Whakareatia te 2 ki te 3, ka 6.
30=x+2y
Whakareatia te 6 ki te 5, ka 30.
x+2y=30
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2y=30-x
Tangohia te x mai i ngā taha e rua.
\frac{2y}{2}=\frac{30-x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{30-x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{x}{2}+15
Whakawehe 30-x ki te 2.
