Kua tāruatia ki te papatopenga
-3x+8=4y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=4y-8
Tangohia te 8 mai i ngā taha e rua.
\frac{-3x}{-3}=\frac{4y-8}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{4y-8}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=\frac{8-4y}{3}
Whakawehe -8+4y ki te -3.
4y=8-3x
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{8-3x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{8-3x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{3x}{4}+2
Whakawehe -3x+8 ki te 4.
