30000-600-\left(-23x\right)\leq 80000
Hei kimi i te tauaro o 600-23x, kimihia te tauaro o ia taurangi.
30000-600+23x\leq 80000
Ko te tauaro o -23x ko 23x.
29400+23x\leq 80000
Tangohia te 600 i te 30000, ka 29400.
23x\leq 80000-29400
Tangohia te 29400 mai i ngā taha e rua.
23x\leq 50600
Tangohia te 29400 i te 80000, ka 50600.
x\leq \frac{50600}{23}
Whakawehea ngā taha e rua ki te 23. I te mea he tōrunga te 23, kāore e huri te ahunga koreōrite.
x\leq 2200
Whakawehea te 50600 ki te 23, kia riro ko 2200.
