Tohaina
Kua tāruatia ki te papatopenga
4h+48+3\geq 19
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te h+12.
4h+51\geq 19
Tāpirihia te 48 ki te 3, ka 51.
4h\geq 19-51
Tangohia te 51 mai i ngā taha e rua.
4h\geq -32
Tangohia te 51 i te 19, ka -32.
h\geq \frac{-32}{4}
Whakawehea ngā taha e rua ki te 4. Nō te mea he >0 te 4, ka noho pērā tonu te ahunga koreōrite.
h\geq -8
Whakawehea te -32 ki te 4, kia riro ko -8.
