3.5x<-30-10
Tangohia te 10 mai i ngā taha e rua.
3.5x<-40
Tangohia te 10 i te -30, ka -40.
x<\frac{-40}{3.5}
Whakawehea ngā taha e rua ki te 3.5. I te mea he tōrunga te 3.5, kāore e huri te ahunga koreōrite.
x<\frac{-400}{35}
Whakarohaina te \frac{-40}{3.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x<-\frac{80}{7}
Whakahekea te hautanga \frac{-400}{35} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
