Kua tāruatia ki te papatopenga
y=18-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 6-x.
18-3x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=y-18
Tangohia te 18 mai i ngā taha e rua.
\frac{-3x}{-3}=\frac{y-18}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{y-18}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=-\frac{y}{3}+6
Whakawehe y-18 ki te -3.
y=18-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 6-x.
