Kua tāruatia ki te papatopenga
3<3x-5
Pahekotia te 7x me -4x, ka 3x.
3x-5>3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
3x>3+5
Me tāpiri te 5 ki ngā taha e rua.
3x>8
Tāpirihia te 3 ki te 5, ka 8.
x>\frac{8}{3}
Whakawehea ngā taha e rua ki te 3. I te mea he tōrunga te 3, kāore e huri te ahunga koreōrite.
