Kua tāruatia ki te papatopenga
x=-3\left(y-3\right)
Whakawehea te -6 ki te 2, kia riro ko -3.
x=-3y+9
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te y-3.
x=-3\left(y-3\right)
Whakawehea te -6 ki te 2, kia riro ko -3.
x=-3y+9
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te y-3.
-3y+9=x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3y=x-9
Tangohia te 9 mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{x-9}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{x-9}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=-\frac{x}{3}+3
Whakawehe x-9 ki te -3.
