4.5+1.3t-3.8t>-3
Tangohia te 3.8t mai i ngā taha e rua.
4.5-2.5t>-3
Pahekotia te 1.3t me -3.8t, ka -2.5t.
-2.5t>-3-4.5
Tangohia te 4.5 mai i ngā taha e rua.
-2.5t>-7.5
Tangohia te 4.5 i te -3, ka -7.5.
t<\frac{-7.5}{-2.5}
Whakawehea ngā taha e rua ki te -2.5. I te mea he tōraro a -2.5, ka huri te ahunga koreōrite.
t<\frac{-75}{-25}
Whakarohaina te \frac{-7.5}{-2.5} mā te whakarea i te taurunga me te tauraro ki te 10.
t<3
Whakawehea te -75 ki te -25, kia riro ko 3.
