Kua tāruatia ki te papatopenga
10\times 2<-\frac{1}{7}y
Me whakarea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.
20<-\frac{1}{7}y
Whakareatia te 10 ki te 2, ka 20.
-\frac{1}{7}y>20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
y<20\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<-140
Whakareatia te 20 ki te -7, ka -140.
