Kua tāruatia ki te papatopenga
-4x=3y+12
He hanga arowhānui tō te whārite.
\frac{-4x}{-4}=\frac{3y+12}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{3y+12}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=-\frac{3y}{4}-3
Whakawehe 12+3y ki te -4.
12+3y=-4x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3y=-4x-12
Tangohia te 12 mai i ngā taha e rua.
\frac{3y}{3}=\frac{-4x-12}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{-4x-12}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-\frac{4x}{3}-4
Whakawehe -4x-12 ki te 3.
