Kua tāruatia ki te papatopenga
y=70-8x+10
Hei kimi i te tauaro o 8x-10, kimihia te tauaro o ia taurangi.
y=80-8x
Tāpirihia te 70 ki te 10, ka 80.
80-8x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-8x=y-80
Tangohia te 80 mai i ngā taha e rua.
\frac{-8x}{-8}=\frac{y-80}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{y-80}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
x=-\frac{y}{8}+10
Whakawehe y-80 ki te -8.
y=70-8x+10
Hei kimi i te tauaro o 8x-10, kimihia te tauaro o ia taurangi.
y=80-8x
Tāpirihia te 70 ki te 10, ka 80.
