-174>-2x+35x-42
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te -5x+6.
-174>33x-42
Pahekotia te -2x me 35x, ka 33x.
33x-42<-174
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
33x<-174+42
Me tāpiri te 42 ki ngā taha e rua.
33x<-132
Tāpirihia te -174 ki te 42, ka -132.
x<\frac{-132}{33}
Whakawehea ngā taha e rua ki te 33. Nō te mea he >0 te 33, ka noho pērā tonu te ahunga koreōrite.
x<-4
Whakawehea te -132 ki te 33, kia riro ko -4.
