Kua tāruatia ki te papatopenga
10x-120=3y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
10x=3y+120
Me tāpiri te 120 ki ngā taha e rua.
\frac{10x}{10}=\frac{3y+120}{10}
Whakawehea ngā taha e rua ki te 10.
x=\frac{3y+120}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
x=\frac{3y}{10}+12
Whakawehe 120+3y ki te 10.
3y=10x-120
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{10x-120}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{10x-120}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=\frac{10x}{3}-40
Whakawehe -120+10x ki te 3.
