Kua tāruatia ki te papatopenga
-3x=4y-20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{-3x}{-3}=\frac{4y-20}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{4y-20}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=\frac{20-4y}{3}
Whakawehe -20+4y ki te -3.
4y=-3x+20
Me tāpiri te 20 ki ngā taha e rua.
4y=20-3x
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{20-3x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{20-3x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{3x}{4}+5
Whakawehe -3x+20 ki te 4.
