-12=-5y+2y-6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te y-3.
-12=-3y-6
Pahekotia te -5y me 2y, ka -3y.
-3y-6=-12
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3y=-12+6
Me tāpiri te 6 ki ngā taha e rua.
-3y=-6
Tāpirihia te -12 ki te 6, ka -6.
y=\frac{-6}{-3}
Whakawehea ngā taha e rua ki te -3.
y=2
Whakawehea te -6 ki te -3, kia riro ko 2.
