Kua tāruatia ki te papatopenga
-\frac{1}{7}y+2>10
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
-\frac{1}{7}y>10-2
Tangohia te 2 mai i ngā taha e rua.
-\frac{1}{7}y>8
Tangohia te 2 i te 10, ka 8.
y<8\left(-7\right)
Me whakarea ngā taha e rua ki te -7, te tau utu o -\frac{1}{7}. I te mea he tōraro a -\frac{1}{7}, ka huri te ahunga koreōrite.
y<-56
Whakareatia te 8 ki te -7, ka -56.
