Kua tāruatia ki te papatopenga
3.2x\leq -3.2+16
Me tāpiri te 16 ki ngā taha e rua.
3.2x\leq 12.8
Tāpirihia te -3.2 ki te 16, ka 12.8.
x\leq \frac{12.8}{3.2}
Whakawehea ngā taha e rua ki te 3.2. I te mea he tōrunga te 3.2, kāore e huri te ahunga koreōrite.
x\leq \frac{128}{32}
Whakarohaina te \frac{12.8}{3.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x\leq 4
Whakawehea te 128 ki te 32, kia riro ko 4.
