-38=-5y+17
Pahekotia te 7y me -12y, ka -5y.
-5y+17=-38
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-5y=-38-17
Tangohia te 17 mai i ngā taha e rua.
-5y=-55
Tangohia te 17 i te -38, ka -55.
y=\frac{-55}{-5}
Whakawehea ngā taha e rua ki te -5.
y=11
Whakawehea te -55 ki te -5, kia riro ko 11.
