Tohaina
Kua tāruatia ki te papatopenga
5x+10y=20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5x=20-10y
Tangohia te 10y mai i ngā taha e rua.
\frac{5x}{5}=\frac{20-10y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{20-10y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=4-2y
Whakawehe 20-10y ki te 5.
5x+10y=20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
10y=20-5x
Tangohia te 5x mai i ngā taha e rua.
\frac{10y}{10}=\frac{20-5x}{10}
Whakawehea ngā taha e rua ki te 10.
y=\frac{20-5x}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
y=-\frac{x}{2}+2
Whakawehe 20-5x ki te 10.
