Whakaoti i te -28+5(7-v)<-2(v+4)

$$- 28 + 5 ( 7 - v ) < - 2 ( v + 4 )$$

Whakaoti mō v

$$v>5$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 7-v.

$$-28+35-5v<-2\left(v+4\right)$$

Tāpirihia te -28 ki te 35, ka 7.

$$7-5v<-2\left(v+4\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te v+4.

$$7-5v<-2v-8$$

Me tāpiri te 2v ki ngā taha e rua.

$$7-5v+2v<-8$$

Pahekotia te -5v me 2v, ka -3v.

$$7-3v<-8$$

Tangohia te 7 mai i ngā taha e rua.

$$-3v<-8-7$$

Tangohia te 7 i te -8, ka -15.

$$-3v<-15$$

Whakawehea ngā taha e rua ki te -3. I te mea he tōraro a -3, ka huri te ahunga koreōrite.

$$v>\frac{-15}{-3}$$

Whakawehea te -15 ki te -3, kia riro ko 5.

$$v>5$$
